Wasn't sure where to put this, but it seems like more of an electrical thing than an engine thing (at least thats what I'm hoping)
Anyway...Xterra was parked at the airport for 3-4 days while we were out of town. Hopped in and turned the key to ACC (did not turn on the engine)to roll down the windows while we put luggage in and air out the car. Noticed the Oil Pressure gauge went straight to max. Thought it was odd, but also thought that once engine was running it would level out.
Nope...started up just fine, no weird noises ran normal. Gauge still sitting on high. Needle was 100% motionless. No fluctuation with RPM...nothing. Turned it off, checked oil (which was fine). Turned to ACC again gauge pegs, start engine, needle remains.
Xterra has 155K, synthetic oil EVERY 3-4 K. Checked oil filter, no leakage, no ballooning.
First course of action will be an oil and filter change.
Next, I'm guessing will be replacing the oil pressure sending unit. Which brings me to my question.
Where the heck is the oil pressure sending unit :scratch: ??
Is it just a plug and play kind of deal? I think I can source one from the dealer for $$$ or probably from Rockauto for cheaper.
I'm hoping its not the oil pump or a plugged oil passage or something. :surprise:
Any other stuff I should consider?
Thanks everyone in advance!!
