1996 S10 2.2 2WD Truck
1996 S10 2.2 2WD Truck
Daily driver to and from work 3.5 miles. I do this run 3 times a day. When I drive 30+ mile one way, freeway/highway, on the return run P0137 activates SES. SES clears within 4 - 5 days if driving to and from work 3.5 miles. New OS. HOS, temperature sensor located under new 180 degree thermostat(original was 180). Any idea way P0137 trips? |

Could be several things.
Weak 02 sensor /02 sensor heater circuit or wiring and plug in or even VCM/PCM computer problem. Engine running problem can also cause the code. Needs proper testing and put on a good engine capable scanner that will read out and test 02 sensor. Any other codes? MT

No. No other codes. I guess I could switch OS/HOS back to old ones and compare results. That's a cheap test.
