What else can I help you with?
The check engine light is on the Auto Zone computer listed a hex code 3e but with no definition Do you know what this code is?
Chilton's manual shows 3E (PO 132) as the left upstream oxygen sensor shorted to voltage.The oxygen sensor input voltage is too high. The problem is in the oxygen sensor itself. (must be replaced) or in the Mini computer unit (MCU) The MCU controls input voltage to the oxygen sensors to control fuel flow. Good Luck I hope this helps
Will oxygen sensor keep 1996 blazer from starting?
Nope. The computer doesn't even look at the oxygen sensor until the oxygen sensor reaches operating temperature.
What does code P0135 mean on 2006 cobalt?
The code refers to the front oxygen sensor on bank 1. That O2 sensor needs to be replaced or the wiring has come loose or is shorted out.
What is an oxygen sensor?
An oxygen sensor is a device that measures the oxygen in a car's exhaust. The computer uses this to adjust the amount and timing of fuel injected.
Jeep code poo51?
02 Sensor Heater Control Circuit Low (Bank 2 Sensor 1) Shorted condition detected in the oxygen sensor heater element control feedback sense circuit
What does an oxygen sensor do for a truck?
The computer uses the oxygen sensor reading from the exhaust to adjust the amount of fuel injected into the engine.
Does your o2 sensors control your idle?
Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing. If an oxygen sensor is malfunctioning, it could cause idle problems.Not directly. The oxygen sensor measures oxygen levels in the exhaust. The computer uses that to calculate fuel and spark timing.

How you can test the oxygen sensors?
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
What rear oxygen sensor does?
The rear oxygen sensor looks at the percentage of oxygen in the exhaust after it has passed through the catalytic convertor. The computer compares this with the reading from the front sensor to tell if the catalytic converter is working correctly.
Could oxygen sensor fAILURE Cause sputtering in 1998 gmc truck?
yes the oxygen sensor will cause the computer to detect a real rich fuel mixture and try to compensate for this input at the computer .
Why does the temp sensor light on a 1990 VW Jetta still come on after replacing both sensors?
Defective new sensors, shorted wire, defective computer
How do you know when oxygen sensor is not working?
The computer will tell you. If you have a "check engine" light, connect a code scanner to see what the computer has detected. If there is a problem with the oxygen sensor the code scanner will display the appropriate problem code.
