Question about Mercury Villager
Hi, code 340 is for the camshaft sensor. Below is a test you can run to check the sensor. The PCM is above the glovebox. Do not disconnect or remove the PCM. Just remove the glove box and probe the back of the connector to access the pins indicated in the cam sensor test. Please let me know if you have any questions, and thanks for using FixYa.
On 1999-00 vehicles, the camshaft position sensor must be checked with the engine running. If a no start condition is encountered, observe the MIL. With the ignition switch on and the engine off, the MIL should be illuminated. If the camshaft position sensor is functioning, the MIL should go out when cranking the engine.
REMOVAL & INSTALLATION
The camshaft position sensor is part of the distributor assembly, and must be replaced as a unit. Please refer to Engine Electrical, Distributor Ignition System, Distributor, Removal and Installation for the procedure.
