P1133 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor
You will need to check the output signal from this O2 sensor, if the voltage low (.10-.25 volts) try spraying propane into the air cleaner to see if the O2 volts go up, it should go to around .75 volts, if nothing happens then the O2 sensor is bad, bank #1 O2 is on the same side as #1 cylinder
PLEASE RATE THIS INFO.

What does the code P1133 mean


Code 1133 is when the O2 sensor in front of the catalytic converter on bank one does not switch back and forth between rich and lean.
The problem could be a faulty sensor or something with the fuel mixture. The sensor would need to be tested.

Check engine light code p1133 on a chevy colorado 2005


The code means the ECM doesn't like the exhaust mixture coming thru the cat.
It could mean one of the O2 sensors has failed, but could also be caused by a list of other problems with the fuel-air mixture.
If the ECM can't adjust the fuel trim to keep in the range, the cat could be damaged and fail inspection, so the ECM turns the light on and goes into safe mode until the problem is fixed.

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

Codes 1133-0131-0171-0300


p1133 - o2 sensor, Insufficiant Switching, Bank 1 Sensor 1.
p0131 - o2 sensor circuit, low voltage, bank 1 sensor 1
p0171 - Lean condition, Bank 1
p0300 - Random Misfire

I would be looking at the front passenger side oxygen sensor for issues. It may be bad, it may not be plugged in, bad wiring at harness.

The random misfire may be symptomatic of the o2 sensor problem.
