I need some help...
I bought the knock sensor from auto anyhting for an xterra SC for 118 bucks
Mounted the sensor in the same location. I spliced into the two wires on the front side of the connector. The two wires are the bottom two all the way to the right hand side if youre looking at the connector. I cleared the code...it came back, so I switched the two wires ont he terminal, cleared and then came right back on. What am I missing?
$118? I think the part from Nissan was only $78.
The only thing I can think of is are you sure you have the right wires? Nissan is notorious for changing wire harness color codes even within a model year and it's not always reflected in the ECM. Also, in my picture, I had twisted the plug upside down for clarity to take the picture. Mine's a 2002, if that helps any.
If the code is coming up immediately, more than likely that means there is no voltage getting to ECU. Can you read the code? are you getting P327?
Another possibility is to be sure the knock sensor is well grounded. Clean the mounting area very well and try again. 2.5 volts won't arch over much dirt.
