Question about Chevrolet Colorado
I have a 1998 Chevorlet Monte Carlo, and a I just got a p1133 code a week ago. I have my own diagnostics equipment, and the code is for "Oxygen sensor insufficient switching(upstream)"
I believe the codes are manufacturer specific so the code should be the same for all chevy's. The upstream oxygen sensor is located in the exhaust system before the catalyic converter. An ideal voltage for the sensor is .45v, but the sensor should switch between .1 and .9, when there is insufficient switching it causes the engine to run both too lean and too rich at times. Too lean could cause the engine to missfire and run rough. Hope this helps.
