Will need scanner to ckeck TPS% from closed throttle to wot. KOEO.
Scanner can read codes but can,t read Data stream. It gives a no communication info. I use snap-on solus pro. When I Erase the DTCs and recheck after i get ( No DTC detected) but the Malfunction indicator Lamp(MIL) will not go off. I have replace the throttle twice.
What is the code(s) must be hard fault if lamp won't go off. Most all scanners can read
Thanks for your quick response. please these are the codes:
P0123 Throttle position sensor switch A circuit high input
P2103 Throttle actuator control motor high
P2135 Throttle/Pedal position sensor switch 'A'/'B' voltage correlation.
When I Erase the scanner shows no faults but the MIL will still be on.
The fault is intermittent.
Thank you all for your help. I have managed to solve the problem with the Corolla. it was the Electronic control Unit. (ECU)
I'm most greatful to you all.
seek diag and est to determine problem a scanner will be needed
