Bank 1 is the frt side exhaust manifold (did they say bank 1 sensor 1?),you can start by replacing that sensor,i would check the intake for leaks ,the gm 6cly. are known for bad intake gaskets,you will see oil coming out form the frt or rear of the intake,also check your atifreeze overflow bottle for bronwish sludge,which means that the oil is mixing with the antifreeze.A leaking intake could cause that lean condition.

SOURCE: 2002 Pontiac Montana, No Heat, I put the temp control on

the cabel from the heat dial to the heater box behind the dash could be snaped or jamed thus not opperating the lever which operates the flap which open and closes the heat box next to the matrix. or if your coolant is brown in colour it could be your matrix is clogged with sedament and needs flushing out. or it could be your water pump not pumping coolant round your engine or it could be a knackerd thermostat i hope these will help you id start with the easyest first thermostat

O2 sensor are located before and after Catalytic Converter ( exhaust system of your car). If you car's engine is 4 cyl you have 2 O2 sensors and if you car's engine is 6 cyl then you have 4 O2 sensors ( for each bank, 2 for left bank and 2 for right bank). Hope it helps and comment if you need more advice. Please don't forget to rate the answer it helps with my ratings, thanks!

Location of o2 sensor

the o2 sensor is on you exhaust pipe between or on the catlic converter

Apr 12, 2014 | 2002 Pontiac Montana

1 Answer


This code sets because the onboard computer senses that the exhaust quality before vs. after the catalytic converter do not meet design specs. It determines this via the upstream and downstream O2 sensors in the exhaust.
Possible causes are:
Poor engine performance.
Damaged/defective converter
Damaged/defective O2 Sensor(s)
Exhaust leaks

Fluctuation engine temperature interior heat stops when engine temp goes up. engine makes clatter noise at times

Getting P0135 and P0301 also in this Montana. I'm guessing its the upstream O2. (bank 1, sensor 1)

Changed the thermostat, and the oil and antifreeze is clean and clear.

Any tips or tricks on how to tilt engine to change O2?

Service Engine soon light on - diagnostic code says o2 sensor. What is an O2 sensor and is it hard to replace

You'll need to give us the specific code, in the format P0xxx. Just saying "O2 sensor" doesn't mean anything. It could be the heater circuit, fuse, o2 sensor itself, etc. Changing an O2 sensor isn't too hard but you may not need to replace it/them.

Please report back with the code or look it up at
