Is the O2 sensor heater on my Silverado Sierra?
Recently purchased a 2001 Silverado in private sale. The previous owner had recently replaced fuel pump and had an exhaust leak fixed (included all maintenance records with sale). I went to get it tested at emissions (Arizona) but they would not test it as apparently the ECU was cleared and not all tests (O2 sensor heater) had rerun.
Where are the sensor locations on a Chevy Silverado?
Repair Topics > Electrical > Sensor Locations > Chevrolet Sensor Locations > 2010 Chevrolet Silverado… Accelerator Pedal Position (APP) Sensor Above accelerator pedal.
