cg084 Posted November 20, 2003 Share Posted November 20, 2003 Hello, I have the engine diagnostic code 42 displaying. Which according to this brill site is the speed sensor No1. Does anyone know whether this part is readily available should it require replacement. Or is it a trip to a Jap Importers? Cheers cg084.

Willson Posted November 20, 2003 Share Posted November 20, 2003 Seems to be pretty common this. I get it occasionally. From what I've read, the most likely causes are a problem with the speedo conversion or the odometer, which resends the speed signal round the car. More likely an electric issue than the actual sensor being faulty. Not a lot of help ............. I would see if you can get Pete TRL to look at it, or maybe Toyota ?

Steve W Posted November 20, 2003 Share Posted November 20, 2003 I got "Speed Sensor" code when I got mine.... it turned out to need the old 'convertor' ripping out and I fitted Pete Betts "box".... NO MORE CODE. [my 'symptom' was if I held 3,000 rpm plus for more than 8 secs, the E'Managment light and Warning Triangle stayed on until ignition off/on] FatS.

Willson Posted November 20, 2003 Share Posted November 20, 2003 I'd like to try changing the speedo converter, but I can't find it ! I've had the dash pretty dismanlted but no joy. Quote Link to comment Share on other sites More sharing options...
Steve W Posted November 20, 2003 Share Posted November 20, 2003 As you said, it's Tee-d into the Speedo and Odo 'IN' wires.... and then there's a box / or 'card' attached and laying/stuck just nearby ?? THAT IS if your speedo reads up to 180 MPH ?? (if it just reads to 120 MPH then it's obviously not 'converted', just re-faced ??) FatS.

Willson Posted November 20, 2003 Share Posted November 20, 2003 Yeah 180 clock. I've had a damn good look, but I guess I'll check it again sometime..... one day...... probably in the summer........ maybe..... Quote Link to comment Share on other sites More sharing options...
cg084 Posted November 21, 2003 Author Share Posted November 21, 2003 Hi, Well i have had the car in my local garage this time and they have had the diagnosis check and they have tested various things. They then reset the ECU. But as ihave found out the light has come back on again. It only seems to come on when the engine is warmed up and i am doing about 55mph about 2500 rpm and higher. If it is as you suggest an improper MPH conversion how do i go about checking and making it a proper conversion. I know how to reset the ecu by taking out the fuse for efi1. Hope you can help.

Steve W Posted November 21, 2003 Share Posted November 21, 2003 Mate... sit at ~2,800 for ~10 seconds... THEN, go to ~3,500 and SIT..... IF it goes ON after ~8/9 secs then likely to be same as mine was !? Quote Link to comment Share on other sites More sharing options...
cg084 Posted November 24, 2003 Author Share Posted November 24, 2003 Hi all, I am still having a problem. wit this. Car is going back in to the garage this week again. It has had a dig tool plugged in and they told me that it is err code 24 an air sensor. But the symptoms i get are that of 42. I really like the car but is it worth it with all these garage trips. When am i going to get to drive my lovely car. It only comes on when the engine is warmed up. Only when i am going above 55 MPH. I have had the car for just a couple of days over a week. Seriously thinking about taking it back getting my dosh back and waiting to get a TT. My only other alternative is scraping some money back from the dealer i got it from. I found the local Toyota dealer unhelpful. Lots of HMM and import. We will have to see whether it will this and that. Fed up to be quite honest. Going to give it one more try with the garage then i am going to rid my self of it. Pitty since it is a nice car when i get to drive it. Before i forget it has also started cutting out mostly when i am changing gears on the move. Tonight it was while going from 4th to 5th gear. Was not giving any well and was going down hill. It has done it on the flat when waiting to pull out of a junction and also when going along on a flat. :( Quote Link to comment Share on other sites More sharing options...
Willson Posted November 24, 2003 Share Posted November 24, 2003 Do you have an active spoiler. If so that is when it would be deployed (60mph). Same as mine. Toyota garages can be a bit funny with the imports. They are all different. They are not really very knowledgeable about our cars anyway. Best to go to a specialist. It does get very annoying when your car is not well though. Easy to go off it at the time. I would tell the dealer you're not happy, there are plenty of supras around. I'm pretty sure Pete at TRL (on here) would be able to sort it for you though, If you want to keep the car. Might be worth sending him a message. All waffle really, maybe some vague sense in there......... Quote Link to comment Share on other sites More sharing options...
cg084 Posted November 24, 2003 Author Share Posted November 24, 2003 Hi, No active spoler on mine. Jus a plain old SZ with no extras. From other postings i can only assume a botched conversion to MPH on the speedo. But i have no other real way of testing it. Other than if all the sensors have been tested it would appear to be the most logical choice. But the dealer speacalises in Imports. I must assume that that they would know the best converter to go for. Otherwise they would have had other complaints. Cheers Quote Link to comment Share on other sites More sharing options...
Willson Posted November 24, 2003 Share Posted November 24, 2003 If they *really* knew what they were doing, they could fix it. The conversion might be okay on 99% of the cars they have done. I would go straight to the top and get an expert (Pete) to look at it, if you can (and want to keep the car). Just my opinion though. Maybe other people can sort it too. But If it was me, thats what I would do. Tell em to fix their car, or give it to someone who will, or give you your money back I know dealers can be a nightmare to deal with though On the plus side, it's not really a serious problem in itself.

mos Posted December 3, 2003 Share Posted December 3, 2003 There are a few fixes for this and it may not be the conversion at fault, you need to check all the soldered joints on the oddometer as a dry or cracked solder will cause code 42 to light up.

cg084 Posted December 3, 2003 Author Share Posted December 3, 2003 Hi, When you say a bad solder would that cause the speedo to not operate correctly. I will have a look at the back of the speedo when i get my car back. Only had it about 2 weeks then crashed it while some git shot out in front of me and left the scene of the accident. Broke my car and was gone by the time i got out of it. Needless to say i am fuming :flame Dev Quote Link to comment Share on other sites More sharing options...
mos Posted December 5, 2003 Share Posted December 5, 2003 It could cause the speedo to not work depending on where the cracked solder is but mine was actually inside the oddometer and just gave me code 42. Next time it happens check if the oddometer is still counting and that will help guide you to the problem. Quote Link to comment Share on other sites More sharing options...
cg084 Posted December 15, 2003 Author Share Posted December 15, 2003 Hi, After thinking more about this problem i decided to take the speedo out of the car to look at the signal converter. After looking at this the gare that fitted it. (The place where i bought the car from had just cut the Blue/Red wir to the speedo and twisted the signal in (KPH) wire toward the wiring loom end of the Blue/Red wire. They had also twisted the Signal Out (MPH) wire to the speedo end of the Blue/Red wire. The only other wires connected were the posotive and earth leads. These are simply fastened to 2 seperate screws on the back of the Speedo. I had to tidy and place proper connectors on to the wires but i still have the problem with the Light. The speed sensor has now been replaced. The only difference is the length of time it takes for the light to come on. It takes a little longer. As for the signal converter it is a rather small unit only about 15mm thick, 20mm wide and about 25-30mm in length. Looks rather cheap. I would like to know whether the fitment of this converter is what is causeing the warning code 42 to display on my pride n joy. Hope someone can tell me whether there could be a problem. Cheers for the help to all those above and below. Craig. Quote Link to comment Share on other sites More sharing options...
Willson Posted December 15, 2003 Share Posted December 15, 2003 I personally would replace it with a TRL unit, they are not expensive. Quote Link to comment Share on other sites More sharing options...
mos Posted December 15, 2003 Share Posted December 15, 2003 It could be the speed converter but as i say take a look at the oddometer both inside and out, even more so if you have taken the dash out a few times it only takes a minute so have a look before you chase the wrong thing Quote Link to comment Share on other sites More sharing options...
cg084 Posted December 17, 2003 Author Share Posted December 17, 2003 All, Still no joy with this. The car has warranty from the garage i bought it from but when i called to get all this sorted sincei have also had a problem with the lower suspension arm and a wheel bearing the warranty company tells me that it is not covered in the warranty i got with the car and the garage i bough it from does not return my calls. Bit of a pain i traded a 2.6 Audi A6 for this and i believe that i am seriously regretting it now. Spoke with my local garage and although they are unsure about the Speedo Converter they are having the car back again for a 4th time now to check over the car yet again. But so far the bill for repairing this wallet monster is at £800 and the bill is going to rise with this trip in to the garage. None of this appeared to be wrong on the test drive but the engine warning light only comes on at 50 mph or higher once warmed up. Bit difficult to get to these speeds in the middle of birmingham. And i do believe that my eyes could not have noticed the slight bend in the front Lower suspension arm. Which since that was changed it was revealed that a new bearing would be needed. Hoping to have sorted this out by xmas but now it seems i will have the car back and i will be forced in to overdraft. If i get any more news i will kep you posted and any more problems from the supplier of my car (where i bought it from i will go so far as to name and shame. Hope noone falls in to the same trap especially since they have another Supe for sale. Older year though.

mark brown Posted December 18, 2003 Share Posted December 18, 2003 Check the speed converter and wiring to the converter first. There is loads on info on this site regarding this. However I had exactly this problem and after checking everything else it turned out to be faulty odometer, although it appeared to be working ok. A replacement is not expensive, if it is this, about £38. Mark Brown Quote Link to comment Share on other sites More sharing options...
fjza63 Posted December 19, 2003 Share Posted December 19, 2003 I had this fault it was just a loose connector on the back of dash due to plastic clip being broken on the warning light display panel on right side of steering. garage wedge wire terminal in after checking contact pins (no more warning light) might be worth checking them all?? as it sounds you've had dash out a few times.
