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
