Do I need a new ECM?
Hi folks
My check engine light came on and I got the following codes:
0228 - M16/6 (Throttle valve actuator) Throttle valve jamming (iced up) P0638
1337 - Alternator serial interface
0217 - Throttle Valve stiff P2176
0569 - G3/3 (left O2 sensor before TWC KAT) Voltage is too high P2240
So I got a new alternator, a new throttle valve and 4 new O2 sensors. Cleared the codes, reset the ECU and the codes still appear. Other weird things are happening - one headlight turns off when I turn; dashboard says number plate light is blown, but it's not; same thing with park light; auto side mirror sometimes works.
Mechanic says that ECU is bad. Read in this forum (SunnyRayToronto sounds very knowledgeable!) that ECU's don't go bad like that and it may be something else. Car runs normally.
Could it be that I have a bad ECU? or do I just have several problems... will CRC contact cleaner work?
