Pontiac Montana Replacement Oxygen Sensor Information
If you're driving a Pontiac Montana whose computer trouble codes have indicated a problem with the vehicle's oxygen sensor(s), you'll be pleased to know that on your vehicle there are only two O2 sensors, whereas on most other vehicles there are a total of three or four. Oxygen sensors, which resemble spark plugs in appearance, are fitted into your minivan's exhaust system, one between the engine and the firewall (upstream) and one in the exhaust pipe aft of the catalytic converter. These sensors communicate with your engine's control computer, relating the oxygen content of the exhaust gases. The upstream sensor provides info the computer uses to regulate the air/fuel mixture, among other things. The downstream sensor relates how efficiently the catalytic converter is operating. A bad oxygen sensor should be immediately replaced. PartsGeek.com carries a complete line of replacements for the 1999-2009 Pontiac Montana.
