P0340 Camshaft position sensor circuit P0340 (M) No Cam Signal At PCM No fuel sync.
Trouble code P0645 means:A/C clutch relay control circuit
Codes P0344 and P0340 indicate issues with the camshaft position sensor or its circuit. To fix these codes, first, check the camshaft position sensor and its wiring for any damage, corrosion, or loose connections. If the sensor appears faulty, replace it. Additionally, inspect the related components and clear the codes to see if they reappear after repairs.
Trouble code P0340 means:Camshaft position sensor circuit malfunction
Trouble code P0340 means: Camshaft Position Sensor A Circuit (Bank 1 or single sensor)
The codes P0300 and P0304 indicate random/multiple cylinder misfires and a misfire specifically in cylinder 4, respectively. The P0340 code points to an issue with the camshaft position sensor, which can affect engine timing and cause misfires. Possible causes for these codes include faulty spark plugs, ignition coils, fuel delivery issues, or a malfunctioning camshaft position sensor. It's advisable to inspect these components and perform a diagnostic to pinpoint the exact cause.
Nice answer. For any vehicle, try looking up your codes here: http://www.obd-codes.com/trouble_codes/
Get your car to a shop to scan the codes. There are well over 100 different codes that can cause your Check Engine Light to come on.
You need a scan tool to read fault codes.
P0455 and P0452 have to do with fuel vapor leaks, will not cause a starting problem. P0340 is a cam sensor code. You need to diagnose for a failed cam sensor.
The codes you provided for the 2000 Dodge Stratus indicate multiple issues. Code PO138 refers to a problem with the O2 sensor circuit, while PO171 signifies a lean air-fuel mixture, suggesting a potential vacuum leak or fuel delivery issue. PO300 is a random/multiple cylinder misfire, and PO302, PO304, and PO305 specifically point to misfires in cylinders 2, 4, and 5, respectively. Together, these codes indicate both fuel system and ignition issues that need to be diagnosed and repaired to restore optimal engine performance.
The computer has detected a malfunction. Sugest that you have it checked for codes. Could be anything from a cracked vacuum hose up to an internal engine problem.
Problem with the transmission. You need to have the transmission computer checked for codes to know a possible cause.
