Hey guys, I installed a few parts like the twin oil coolers, y-pipe and intakes recently and once i was done and connected the battery, the car started, but with the check engine light...pulled the code and it was 2 long flashes meaning code 20, Oil Metering Pump position sensor short something...

Well, with my mods what can be the source of the issue, i know the pump cant be bad because it was fine just before the install, and what determines the position of the pump anyways, i know its driven by the ECU itself and the gear inside the front plate!!! I was told most electronics are inside the pump...so im confused

Any Ideas? Because I cant figure this out...all the connectors are plugged in no problem!!!

 

Start by checking the wiring the pump. Make sure the connection to the emissions harness is good and that you have continuity from the emissions harness down to the pump.
