Can't get 2004 Dodge SRT-4 to start, everytime it gives me the code for the camshaft position sensor malfunction. This sensor has been replaced twice, plus the crankshaft sensor. All electrical connections have also been cleaned with an electrical cleaning spray. What else could possibly be making it code everytime and not start?

EOBD II Error Code:P0117 Fault Location:
Engine Coolant Temperature (ECT) Sensor (G62) - Low Input Possible Cause:
Malfunction Indicator Lamp (MIL) Triggered on first occurrence.
Coolant thermostat.
Wiring short to earth.
Engine coolant temperature (ECT) sensor.
EOBD II Error Code: P0340 Fault Location:
Camshaft Position (CMP) Sensor A (G40), Bank 1 - Circuit Malfunction Possible Cause:
Malfunction Indicator Lamp (MIL) active.
Wiring from/to Camshaft Position Sensor (CMP) faulty.
Camshaft position (CMP) sensor faulty.
Timing misaligned. Possible Solutions:
Check Wiring from/to Camshaft Position Sensor.
Check Camshaft Position Sensor.
Check Timing.
EOBD II Error Code:P0500 Fault Location:
Vehicle Speed Sensor (VSS) - Circuit Malfunction Possible Cause:
Malfunction Indicator Lamp (MIL) Non Emission Fault - No warning light.
Wiring.
Vehicle speed sensor (VSS).
Engine control module (ECM).
Item 2,3,4,5 relate to each other that s camshaft and crankshaft position sensors. Since both already show a malfunction code, it would be advisable to change.
Sometimes other codes show up because there is a relation but not that the item is bad.
P0340 - Camshaft Position Sensor Circuit Malfunction This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
Symptoms can include: Hard starting or no start Rough running / misfiring Loss of engine power
Causes: A code P0340 could mean one or more of the following has happened: a wire or connector in the circuit could be grounded/shorted/broken the camshaft position sensor may have failed the PCM may have failed there exists an open circuit the crankshaft position sensor may have failed
Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try: Visually inspect all the wiring and connectors in the circuit Check for continuity in the circuit wiring Check the operation (voltage) of the camshaft position sensor Replace the camshaft position sensor as required Check the crankshaft position circuit as well Replace circuit wiring and/or connectors as required Diagnose/replace the PCM as required

code p 16 refers to crankshaft position/cam shaft position bank 1 sensor A--correlation====causes ---wiring---CKP sensor ( crankshaft position sensor )---mechanical fault
code p 0340 refers to -camshaft (CMP) sensor A bank 1 circuit malfunction ===causes wiring--CMP sensor--ECM
cosrs nothing to check the timing belt , just remove the oil filler cap and see if the rockers are moving when turning it over
the clue here may be bewteen the 2 codes , the word correlation and circuit malfunction so check the wiring, harness connections for pin corrosion and then substitute the ECM with a know good unit as the correlarion and circuit malfunction could be in the ECM
if the ECM program is not getting good reports for both sensors then it reasons that the piston and cam shaft are not timed properly and so will not allow it to start
That makes the computor think the timing is off. Replace the sensor and see if that does it. You will then have to have the code cleared (erased) or the light will come back on/stay on.
You have to remove the air cleaner hose to the throttle body to access the sensor. I hope it helps. You will see it, its on end of engine. Remove connector then the bolts holding it on. God-Bless! Hope this helps you. The dodge 2.0 is known for bad camshaft sensors, certain years.
