raddys Posted September 4, 2020 Share Posted September 4, 2020 (edited) hi guys My supra has been in the garage for some work, a new heater matrix as mine was leaking into the passenger footwell and 2 new knock sensors. I picked the car up today once I got 10 miles down the road the EML came back on again, I stopped, rung the garage and took it back, he read the code and it said *52, knock sensors. (When I 1st took it to the garage he informed me one was dead and reading no signal so both were replaced) He cleared it and looked puzzled and told me to try it again. I was late getting back home so told him if it came on again id return with the car at a later date. And sure enough about 3 miles down the road i got my EML come back on. This has cost me a pretty penny so far for no change, the car still throwing an EML light for the same problem as when I gave it to them. Anyone else ever had this problem, any help would be much appreciated? (All the guy could think of was that the leaking heater matrix had leaked on the ecu which could be causing the knock sensor code to come up) Thanks Edited September 4, 2020 by raddys (see edit history) Quote Link to comment Share on other sites More sharing options...

raddys Posted September 4, 2020 Author Share Posted September 4, 2020 Try another ECU and find out? That is the next option but I just think that it went in there with a code 52 (Knock sensor) and has come out with the same code after having them done. When it was read initially he saod one sensor was dead so both were replaced. I was under the impression that if coolant got into the ecu it would cause alot more havoc then just a knock sensor code. Either way I suppose trying that next would rule out a faulty ecu Quote Link to comment Share on other sites More sharing options...
raddys Posted September 12, 2020 Author Share Posted September 12, 2020 (edited) so today we tried another ECU, i still have the same knock sensor code EML. When purchasing the knock sensors from TCB PARTS he said he didn't have any supra specific ones but that the celica ones are an exact match. (The tuner recommended i ring tcb however they are closed now) So I'm wondering if anyone can confirm that 2jz knock sensors and celica knock sensors are the same, visually they are but I don't know if they run different due to signals. My tuners reckons I still have the CODE 52 EML problem because they are for a celica, but tcb parts seem very knowledgeable and he said they would work 100% If anyone could shed some light that would be much appreciated. The general running of the engine has also been checked and it runs spot on.
