p0340 code two days after replacement of cmp sensor
1998 3.0 ohv with 125k miles
just purchased this car. after a couple of days, it threw a code, which turned out to be p0340-camshaft sensor (or wiring). i have checked the wiring for both the ground and signal wire, as well as the shielding ground back to the firewall mounting point. all three wires have perfect continuity from the connector to the ecu plug or firewall ground point. so i replaced the sensor, and since the synchronizer was not chirping and the sensor's pickup hadn't fallen inside and mashed it up, i didn't replace the synchronizer.
two days later the code came back. the car runs fine, but gets around 13mpg (i don't have a heavy foot).
anyone have any suggestions?
thanks
