Ford Taurus DTC P0340

Q. My Camshaft Position Sensor (CMP) has my service engine soon light on. What is the reason this code is showing up on my engine analysis computer? I bought a new CMP but my engine light is still on. I replaced the sensor already. I have a 1996 Ford Taurus LX 4 door 6 cylinder.

Thank you...

A. I'm going to assume the code you got was P0340. It is very helpful to me to have the EXACT code the computer has stored. It saves me having to look through almost a thousand DTCs to try and match something up.

The P0340 indicates a Camshaft Position Sensor Circuit Malfunction. The keyword here is circuit. The malfunction can be anywhere in the wiring to and from the PCM or the PCM itself. The code can be set if there is a short to ground, short to power or and open circuit. You need to test the whole circuit before replacing parts.

Also, A special service tool such as Syncro Positioning Tool T95T-12200-A must be obtained prior to installation of the replacement CMP sensor. Failure to follow this procedure will result in improper sensor alignment. This will result in the fuel system being out of time with the engine, possibly causing engine damage.
