Infiniti Repair Questions? Ask a Mechanic for Answers ASAP
Hi,how are you?The camshaft position sensors are located on the back side of the engine on the firewall side mounted in each cylinder head.The p0345 is the code for the exhaust camshaft sensor and this is mounted in the drivers side head and held on by one 10mm bolt and a wiring connector.
Ok great! I have received this information. I also requested "high" level of detail for this and also asked about pricing and the level of difficulty this project might be. Please review the original question to ensure all aspects of the question were answered.
One last question. What would I use to remove the bolt? Should it take 2 hours to complete? Someone was going to do this for me and said the would have to take heads off.
Since you have never done this job,use these steps and it will make it easier.
Bank 2 sensor Driver side:1) Remove the air intake tube from the air filter housing all the way up to the throttle body. 2) Remove the the throttle body electrical connector. 3) Remove the throttle body . It's held in place by 4 hex bolts. Remove all 4 bolts and the throttle body will come right off. Just below it is the casen. 4) Remove the PCV hose (Large black hose which connects from the manifold to the air intake tube). 5) Unclip connector from sensor. 6) Remove 10mm bolt from sensor and pull. The sensor may be difficult to remove from it's orifice. The O-ring that seals it my be making it difficult to remove. Just keep pulling and it will come out.Re-installation: Install all parts in reverse order as above.
Bank 1 sensor Passenger side:This sensor can be removed without removing any parts. 1) Unclip connector from sensor. 2) Reach back with a 3/8" drive socket wrench with a 3" extension and a standard (as opposed to deep) 10mm socket. Unbolt the sensor and replace.Replace sensor in reverse order of removal
Don't forget to rate the answer for me.Here is a procedure if you do not have a scan tool to reset the ecu to turn the light off.
Basic ECU ResetProcedure:1. Confirm that accelerator pedal is fully released, turn ignition switch "ON" (NOT start) and wait 3 seconds.2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.2a. Fully depress the accelerator pedal (HARD).2b. Fully release the accelerator pedal.3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.4. Fully release the accelerator pedal (while the CEL is still blinking)5. Wait about 10 seconds.6. Fully depress the accelerator pedal and keep it for more than 10 seconds.7. Fully release the accelerator pedal (The CEL light will continue to blink).8. Turn ignition switch to "OFF" position and now you can start the car. The CEL light should be gone. If the CEL light continues to remain ON, repeat the above steps. Remember, timing is EXTREMELY critical to resetting the ECU.
One last thing here is how the sensors look on the engine.
Thank you! Excellent Service!
