    this can be caused by a loose cam belt.

SOURCE: Check engine lite says the Throttle Postion Sensor is Bad

The TPS is usually located on the inlet manifold at the rear of the engine.If you look at where the accelerator cable connects to the throttle housing it should be there. It's held on by 2 torx or hex head screws & has a wiring block connector with 3 wires going in to it. This connector should simply pull off when you squeeze the clasp. You didnt say which engine you have but the TPS is similar across the range. You must make sure the ignition is off when unplugging it otherwise you will generate a fault code in the Engine Managment System. Once replaced switch the ignition on for 5 seconds & then switch off. This should position the sensor ready to start the engine.

SOURCE: 2001 saturn sc2 gets code 341&340 camshaft sensor

if you have high resistance in secondary ign. system (plug wires, ign.coil) this will cause this code to set. make sure you are using a high quality spark plug wire set. not from autozone!!! and denso non platinum tipped spark plugs. also use a diaelectric grease on plug wires to keep moisture out.

SOURCE: CODE PO 340 SENSOR CIRCUIT CAMSHAFT 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.I hope this helps you

SOURCE: Diagnostic code P 340 and P 341 Camshaft Position

The Camshaft Position Sensor tells the PCM (computer) the position of the Camshaft Position. This Sensor sychronized along with several other Sensors including the Crankshaft Position Sensor the firing of the electronics to the spark plugs of each cylinder.
It is not difficult to replace and relatively inexpensive.
1. Disconnect the Negative side of the Battery,
2. Locate the Sensor and unplug.
3. Remove the Position Sensor retaining bolt.
4. Pull out the Sensor.
Replacement is reverse of above order.
Hint: use fresh engine oil on the end/sides of the Sensor especially around the rubber o-ring(s) to ease pushing the Sensor into proper position.

SOURCE: I got a camshaft position sensor malfunction code P0340.

it sounds like you have bigger problems if your car does not crank(turn over) then your timing belt could have broken and the one piston could be hitting a valve causing it to be locked up.normally when any sensor is bad car engine still cranks it just doesn't start.

2005 Kia Optima won't run, CodePO338?


error code PO 342 was on the low input. Now the code you are getting is on the problems on the high output for the same Camshaft position sensor. Something "now" is putting out too much juice and can only assume it has to be in the ICM (ignition module) or the coil. If not qualified to do the readings yourself, you will have to take it to someone who can do it.

I have a diagnostic code 340 and 320 on a 1997 Jeep Cherokee. What might the problem be?


DTC P0340 - Camshaft Position Sensor Circuit Malfunction
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

DTC P0320 also have with this wrong.

Check engine light bmw 325i code 340


Code PO340 "Camshaft Position Sensor Circuit Malfunction". Now that does not mean that if you simply replace the sensor your problem will be solved. It can be simply loose, cut, or corroded wiring. It can also be something entirely different. This is where diagnostic skills come in.
