Check engine light on 2005 chevy colorado code p1133

This code is for insufficient switching of the oxygen sensor. Make sure you don't have any other codes, misfires, vacuum leaks and/or exhaust leaks as these will affect O2 readings. Here is some more info I found on the web. http://m.engine-light-help.com/?url=http%3A%2F%2Fwww.engine-light-help.com%2Fgm-trouble-codes.html#3331

It's an o2 sensor code. So you more than likley have burnt wires associated with that o2 sensor.
P1133 = O2 Sensor Fault - Insufficient activity (Bank 1 , Sensor 1)You remove the negative battery connection from the negative battery terminal for 10 minutes.

You ALWAYS reset your computer when you do sensor swaps, when fixed erase code, and see if it stays out. your pcm is getting the wrong info from sensor. good-day !

Check engine light came on with code P1133. front oxygen sensor. Replaced sensor, light is still on. Does it have to be reset?

My book says ( GM ) P1133 - HO2S/O2S Insufficient Switching Sensor 1 Or Bank 1 Sensor 1
Be that as it may - to clear the codes in your computer - disconnect the battery for a couple of minutes and see if that clears the codes. Let me know. Thanks
