Why won't my check engine light on Honda crv go off when I changed the 02 sensor?

P0154 02 Sensor No Activity Circuit

P0141 Heated o2 sensor. P0134 Heater 02 sensor circuit, These 02 sensor has a fuse in the engine junction box listed as IGN 1. This supplies 12volts to the heater circuit, check to make sure its not a open fuse. If you already replaced the sensors make sure you clear the code. or it will stay in memory.

the p0135 is a 02 Sensor Heater Circuit. and the p0134 is a 02 sensor circuit with no activity.

If you have a scan tool that shows sensors, you can clear codes and run your vehicle while checking the operation of your O2 sensors. Then check the specifications and compare. If bad, best is to replace bad sensor. If you go online, you may find more affordable parts.

there is either a problem with the wiring going to the front oxygen sensor, or with the oxygen sensor itself. good luck!

P0134 is O2S CKT Insufficient Activity Sensor 1, I do have a Diagnostic chart i can send you for this code, need email address to send to

OK, you have a code PO341 which means their is a problem with the signal the ECU is receiving from the cam sensor. It does not necessarily mean the sensor is bad. It can be one of these things.
1. Cam sensor wiring routed too close to spark plug wiring (causing interference) 2. Poor wiring connection at cam sensor 3. Poor wiring connection at PCM 4. Bad cam sensor 5. Damaged reluctor wheel You replaced the cam sensor and the problem is still there so we can assume that a defective cam sensor was not the problem. Do this.
1. Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.) 2. Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing 3. Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage 4. 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)

Both codes are for the oxygen sensors.
P0134 oxygen sensor on bank #1, sensor #1 is bad.
P0420 oxygen sensor on bank #1, the sensor down by the catalytic converter, is also bad.

make sure to have your mechanic buddy check for correct firing order
and engine compression becasue any thing mising in the cylinders eill cause a misfire code,
and what codes are you geting?
idont belive than you need an 02 sensor because with a present misfire teh o2 sensor will read rich or lean but most likelly rich
