Will oxygen sensor make truck stall - 1988 Chevrolet K1500

Well, i would guess that this is related to a closed loop problem. When you first start your rig, it is in something called open loop and is not trimming the fuel that is injected into the motor. It just goes on a predetermined table. Once the engine warms up, or has been running for a certian amount of time, it will enter closed loop where it starts watching the oxygen sensors to adjust the fuel accordingly. If you had an oxygen sensor that was stuck rich or lean, that could cause this problem and that is where i would start. You can pull up your oxygen sensor readings in live data on a scan tool to see if one is stuck. Here is a video describing some steps to determining if oxygen sensors(AFR sensors) Are working correctly.

Hi Slim Jim,Here's a link to a pic where your oxygen sensor is. 2000 2004 Nissan Xterra Oxygen Sensor O2 Sensor Location V6 Engine Here's another link to some new oxygen sensors.Get the exact fit ones. Oxygen Sensor

You may have 2 problems. The trouble codes are for an oxygen sensor fault. You likely have a bad oxygen sensor, but that usually won't cause a car to stall. If you're having issues at idle, look for vacuum leaks or possibly a very dirty throttle body.

replace oxygen sensor. car is not reading correct amount of oxy in the exhaust due to defective sensor, and stalls it out

a defective oxygen sensor will make vehicles run rough and will stall out

your code must be P0131, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
The solution is you can:
1.Replace faulty sensor.
2.Repair short, open, or high resistance on o2 signal circuit. FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook

It sounds like you have a large vacuum leak after the mass air flow sensor. This would induce a lean running condition and could cause a stall. Check the rubber air intake bellow for cracks or tears. Also check for disconnected or broken vacuum lines.

I would change the oxygen sensor only if the oxygen sensor code comes up showing that the o2 sensor is is not cycling.

Have the car scanned in order to determine what may be causing the stall condition.

Could be throttle position sensor, a air mixture sensor or an oxygen sensor. If oxygen sensor then replace all of them or you will strain the others and then you will have to keep changing out the oldest on like a cat chasing its tail. smile.

Some cars have 2 sensors. The oxygen sensor and the outlet sensor. One checks the O2 level when it goes in , the other checks the output levels on the outtake . Usually located on the outake manifold or the pipe itself under the car. past the catalytic converter.
