CHEVY OXYGEN SENSOR LOCATIONS

2000 Chevrolet S-10

Engine Performance problem
2000 Chevy S-10 4 cyl Two Wheel Drive Manual 150000 miles

Can someone tell me the locations(s) and how many O2 sensors on a 2000 S10 pickup 4cyl? OBD code read P1137. I assume that refers to O2 sensors?

You have 2 one before and one after the converter. P1137 is an 02 code, weather its the sensor or a low voltage problem is another question.

Would you know tha locations of the sensors. I found the rear (after convertor). Also what procedure is needed to check for low voltage to the sensor? Is low voltage a common thing or is it mostyl sensor failure or a bad connection?

Recommended change interval is 100,000, your over by half again. Sensor is between the exhaust maniflod and the converter.
