2001 gls - p0118 & clearing codes question
 

Getting code p0118 - no others.

Common solution seems to be to change the coolant sensor.

Hooked up scanner with cold engine - temp read 120.
Ran it for a bit and read a temp of -40.

RPM's also bounce around.

Could the problem be more than the sensor?

Thanks,
Joe

Replace the sensor, you know the values is incorrect..

Got myself caught up in DIY overthink...

Changed the sensor - no trouble code.

Funny thing though, it is a 2001 (checked the VIN number), but the sensor was 2000. I thought only some European cars did the keep using last years parts til they run out stuff?
