Oil pressure sensor

blomeup647 · 04-02-2007, 08:04 PM

Question???? I tried to change the oil pressure sensor on 2000 LS1. I went to the dealer the sensor they sold me has 2 pins, my old sensor only has 1 pin. I went back to the dealer and they told me there is harness adapter, the new harness adapter has 2 wires, my harness in the car only has 1 wire.

DOES ANYBODY KNOW WHAT TO DO?

I got 95 Z28 with an LS1 in it.

Don't know what's going on - I do know there's a difference in the 98 and the99-02 OP sensor part numbers, but don't know about the pins. 98 is 12559781 and other is 12562267. I'd think a "harness adapter" would have 2 pins for the sensor end, and one pin for the car harness???? TTT for you, maybe someone knows for sure...

Does your old sensor look like this? http://shbox.com/1/op_sensor.jpg

Yeah, actually my oil pressure sensor looks like that one with one wire, but the sensor is in a different part of the block behind the intake. Part number 12559781 is for the sensor that I got from the dealer which has 2 pins. Part number12562267 is for sensor with 4 pins for the newer ls1.

Is it possible your car was using an LT1 sensor, in the LS1 port since it's a '95?
