Sensor connection U.K Tahoe

[Lee H]

New to the Forum so firstly would like to say hi to everyone!
I'm in the U.K and running a 99 Tahoe LT,6" RCD lift, K&N CAI, Shorty headers, Custom Tune, love the truck and it looks huge over here

Looking for some help please, at the front of the engine I have a sensor hanging in mid air and not sure where it should be. The wires run along with the crank sensor wires and carry on about 6" after the crank sensor plug. It's plugged into a black plastic sensor with a hole through it. 2wires
brown/white I think.
Any ideas? Thanks Lee

Is your engine light on?

Hi, strangely no engine light on.
If you follow the loom to the crank sensor there's a plug that goes into Crank sensor then the loom carries on to a 2 wire plug.
On the only picture I can find it looks like it goes near the water pump but it doesn't show enough detail. Thanks Lee

Could be a knock sensor, on my truck the wire goes to the EVO for the power steering.....

Check your drivers side where the spark plugs go it the block.. knock sensor is on that side
