You may be able to take yours down to an auto parts store and get a replacement. The dealership didn't act like it was anything special and just matched it up with the one I brought to them. @bj

Solenoids and most electrical parts cannot be returned. But, it sounds like you already know that. @Shaderia

OH!!!! ALSO!!!! If you're still throwing the P1140 and P1145 codes, would that automatically mean it's both solenoids?

The guy at the dealer who spoke to his technician, explained that the cam shaft senso, or timing position control sensor, (same part) detects or "SENSES" movement in the engine. I've replaced both cam sensors...and they couldn't come up with anything else that would throw those codes except "oil pressure" which I don't think is right. SO....I'VE DECIDED that since the sensors "sense" movement and solenoids move and there's a solenoid on each side near each cam sensor, wouldn't it make sense that the solenoid could also possibly be out? If something in there's not moving and I've kept my oil changes up, so I know there's no 'SLUDGE', and have brand new sensors, I'm thinking the sensors were possibly picking up on something else in the engine. ...and I think it narrows it down to the solenoids.

My dealer reset them for me last time, but the check engine light came back on with the exact same codes. ...wish there was an easier way!

I've already replaced the bay 1 AND bay 2 cam sensors myself and my Pathfinder is still throwing both the P1140 and P1145 codes. (frustrating!) I plan on switching them out to see if they still throw the codes, but again, they are both new sensors. How do you reset the codes prior to just changing out one or both solenoids?

I have a 2007 Nissan Pathfinder. The check engine light came on and the code is P1148, which is a closed loop sensor bank 1. The problem is that my husband changed it and cleared the code but it won't stay cleared. Can anybody help? Hi! I have a 2007 Nissan Pathfinder.

They have a clear description of how the variable (intake) timing works and is worth the read (IMHO). http://engine-codes.com/p1110_nissan.html stating a Possible solution - Change Oil - Replaced Intake valve timing control solenoid valve I just changed the oil and filter, I have little hope that will prevent the code from returning.
