on this 1887 nissian truck 4.2 lit 2 codes come up po110x2 intake air temp. circuit malf. and po340 camshaft positon sensor A-bank 1 Circuit malf. Before i start throwing parts at it how do i know its not an internal thing. I don?t see anything out of the ordinary and i need it fixed to pass emmisions. Any help would hbe appreciated. thanks
For the po1110 check the wires on your temp sensor. I was messing with my air cleaner box on my 97 hardbody and one of the wires broke. You can try to solder them, but I had to replace the entire temp sensor. The cheapest I found was around 50 bucks.
If that is the intake temp sensor. Check the wires and the wire harness connection. I replaced my sensor (cost $80.00) that didn't fix the problem. It was the connector. Later I found there was a recall on that connector.
