I'm having issues with obd2 codes it seems like I'm chasing codes I have replaced several parts and I'm still throwing codes

Welcome. Can you tell us the codes?

Thank you for responding the codes it's throwing is p1135 and a p0021 I'm thinking about replacing the crankshaft position sensor or could it possibly have jumped out of timing ???

I doubt that it jumped timing. It seems to be a fairly common sensor issue.

There is information about this code on page EC-148 in the FSM at the following link.

The right bank is the closest to the firewall. You might try cleaning the sensor and checking the connector.

If it turns out that you need a new sensor, I would only buy an OEM replacement.

I have replaced both camshaft position sensors and both variable timing solenoid is there another sensor I should replace

How is your oil level and oil pressure?

Excuse me my earlier post. The P0021 code points to bank 2. Bank 2 (the left bank) is closest to the radiator. Bank 1 (the right bank) is closest to the firewall. You've replaced both sensors and solenoids. There may be an electrical connection that is breaking down. There may be an oil flow issue.

If the right and left bank use the same parts, I would swap parts from the right to left bank and vice versa to see if the code moves.

I take it you have a code reader that allows you to reset codes?

My oil level is good I do have a code reader and it can clear codes I have replaced both sets of sensors and selonoids unfortunately they vary slightly one sensor is angeled the other is not and the selonoids are specific design right from left the only sensor I haven't replaced is the crankshaft sensor witch shows up as possible being bad under both codes

Hi. Were you ever able to resolve this issue? I am experiencing a similar problem. P1110 and another P1135 on my 2001 Pathfinder LE. Replaced 2 Camshaft Sensors and a Crankshaft Sensor. There are 5 on this model (3 camshaft sensors and 2 crankshaft sensors). Code still appears after driving for about 40+ miles. Having gotten this deep into the sensors, I might as well try the other 2 but was wondering if you had resolved yours.

Well, the p1135 code is for the Intake Valve Timing Control Solenoid Valve which can be triggered by very dirty oil or could be a faulty valve.

Thanks for the reply. Forgot to mention that before replacing the 3 sensors, the 2 Intake Valve Timing Control Solenoids were replaced as well.
