09 Chevy Cobalt Lt, 130K miles, automatic with the 2.2 and 5 lug wheels.
tpms sensors have been replaced but still the dash for 3 out of 4 tires read "--" and the tire light comes on. Is this a computer module (ecm) or something?
One more thing, please.
I replaced the throttle body position sensor and pedal position sensor. It was a P2138 P2135 and it still went into limp mode for the same problem (fuel, fly-by-wire system). clearing the code with Bluedriver scanner (thanks) and disconnecting the battery for a while. then she drives fine for a while. any advice on that also?
One question per post please. Your tire pressure sensor battery is probably dead.
Follow the troubleshooting on obd-codes.com rather than spraying expensive parts at a problem.
