Tattooman Posted August 1, 2006 Author Share Posted August 1, 2006 OK guys I did the error Code check on my car with the Paperclip and it came up with... "ERROR CODES 34 and 42" Quote Link to comment Share on other sites More sharing options...
leelbuk Posted August 1, 2006 Share Posted August 1, 2006 34 - Turbo Pressure Malfunction 42 - Speed Sensor Malfunction See these: http://www.mkivsupra.net/vbb/showthread.php?t=35920 and hopefully someone here can help with error 34 cause I ain't got a clue! But 42 was the same as mine, check wiring near odometer and around the speed delimiter. Quote Link to comment Share on other sites More sharing options...
jackso11 Posted August 1, 2006 Share Posted August 1, 2006 I had that light. It can coime on for several reasons but as you just installed a delimiter 99% chance is that its due to the engine not knowing what speed your car is doing correctly. Does it happen at about 50-60mph? Check all your connections are in the right place and are not faulty. Quote Link to comment Share on other sites More sharing options...
carl0s Posted August 1, 2006 Share Posted August 1, 2006 Did you reset first? Else the code 34 might be stored from yonks ago. Quote Link to comment Share on other sites More sharing options...
Tattooman Posted August 2, 2006 Author Share Posted August 2, 2006 I am still playing with my boost controller and I am trying to fine tune it now and I think as my tubbies have boosted to just over their boost rating that is what has caused the 34 error code. Si I'm gonna take the gain and boost setting down slightly and see what that brings and also reset the ECU. Quote Link to comment Share on other sites More sharing options...
imi Posted August 2, 2006 Share Posted August 2, 2006 Ive got the 42 error code as well......Ive noticed that when the light comes on, the speed sensor on my Apexi reads 70-116 km/h despite the fact that I am doing a steady 75mph.... And normally the speed sensor reads OK....exactly how it should on the Apexi in Km/h so 100 = 60mph. so something to do with the speed sensor, not sure how to fix it.

TigerT76 Posted August 3, 2006 Share Posted August 3, 2006 I've found this thread very useful as i keep getting the same thing happen to me. Normally when i'm excellerating hard and get over 60mph. I did the paper clip check and it showed the same common fault code, CODE 42. Is this easy to fix? And is it still safe to drive around like it?

R3DG3CKO ROB Posted August 16, 2006 Share Posted August 16, 2006 Bought my Sup on Monday and I have the same problem, the guy I bought it from said he thought it was the air flow meter? However, I hooked up my mates GPS and my speedo is about 5 miles out so perhaps it is something to do with that... I'm thinking of taking it to Toyota for a diagnostic and then taking it to Fensport for a full service. Does anyone know how much toyota would charge to hook it up?

I'm thinking of taking it to Toyota for a diagnostic It's nothing to do with your speedo over-reading. The stock ones always over-read. Check for stored error codes and see what it says.
