I have a 2002 chevy impala I changed the 02 sensor and my check engine light is still on and reading the same 02 sensor


You should have a primary and secondary O2 sensor, upstream and downstream. Pre-Catalytic converter and Post-Catalytic converter.
Which one did you replace?

Where are the 02 chevy impala 3.8L o2 sensor locations, I only see three. the top bank one sensor 1 is stripped out, how do i get that one out?


you can apply pressure to the sensor while undoing it to force it out or you will have to cut out the thread area and get an O2 sensor bung hole replacement at an auto supply store and weld into place and install a new O2 sensor. bank 1 sensor 1 is located in the front pipe off the manifold that has cylinder #1 on and bank 2 sensor 1 is on the side that cylinder #2 is on like sensor 1. sensor 3 is the one just before the cat.

PO 341 code on 2002 chevy impala


Hi,
This P0341 code basically means that the powertrain control module (PCM) detected a problem with the camshaft signal. The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position of the cam sensor. This is accomplished through a reluctor wheel attached to the camshaft that passes by the cam sensor. Any time that the signal to the PCM is inconsistent with what the signal should be, this code is set.
NOTE: this code can also be set by extended cranking periods.
Here is a possible solution to the problem;
  • Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
  • Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
  • Visually inspect the cam sensor for damage
  • Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
  • If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)
  • If all checks out okay, then replace the sensor.


Be cool!!!!
