Hey all, truck has been purring along for a solid year without issue.. i love these things, but really appreciate any guidance!! … Right now I have a crank but no start after messing with the VVT solenoid and ITC sensors. 2002 Pathfinder 3.5 SE
This issue started as a p1145…. I decided to switch the intake timing control sensors from the driver side, with the passenger side one, in that hope that the code would follow the sensor and id get a p1146. I cleaned a bit of gunk off both sensors with some throttle body cleaner and cleared the code and drove happy for a while (probably 500+ km, long enough that I’d forgotten about the issue and thought that cleaning the sensor solved it!)…. I also did an oil change a couple of days later.
The p1145 came back a week ago! … Given it wasn’t a p1146 and after trawling the forums… I started to think that it must be the VVT solenoid (driver side) ... So, I took the solenoid off to test it. Removed/unplugged maybe 7 harness connectors in total to get the solenoid.
I tested the solenoid itself with 12v power (it worked and was clean) and tried to test the solenoid harness connector – but I wasn’t getting any clear voltage across it (with the ignition on) … so I fiddled about a bit and figured that voltage probably isn’t supplied to the solenoid unless the engine is running, so I thought I’d put everything back together and call it a day. Well…. I reconnected everything and went to start the truck – cranking strong, but no start. Note: I accidentally left the ignition ON while I plugged it all back in… triple checked I didn’t leave anything unplugged. Doesn’t seem to be immobilizer (that just keeps steadily blinking as usual and I’ve tried both keys) … now I have a whole lot of new codes!! P1490, P1131, P1111, P0447!
What have I done and how can I get my pathy running again!? Any help very appreciated!
