1997 Chevy 5.7 vortex. Codes p0102 and p0340 are reaccuring. Can clear them, but come back on when motor is started. Replaced can postio ing sensor and cleaned the MAF sensor.


check out the throttle position switch with ohms meter, it must be smooth through the full movement and not jump or flutter .

98 Windstar 3.8l code p0340 keeps coming


I'm pretty sure that sensor is a two wire, which produces an AC volt signal back to the computer. You would test it with an analog volt meter while the engine is cranking or running.
It could be a problem with the object the sensor is supposed to be "watching" such as the end of the cam shaft.

Hi, a P1684 is "Battery Disconnected Within Last 50 Starts". I wouldn't worry about that too much.

The P0340 is "Camshaft Position Sensor Circuit Malfunction". I'd definitely look into that code. I found a great article specific to the p0340 code - http://www.obd-codes.com/p0340 - it should give you an idea on what to look for, test, replace, etc. Good luck!
