Check the wiring going all the way down ot the fuse box, and into the dash, is possible there is a small crack, use an electrical tester and test the wire at every 5 inches, you may find it stops current at some point.

the best tester is one with a sharp point, so you can p0oke thru the coating and into the wire.
this way you do not have to shred the coating in a million places.

What are the probable causes of DTC P0340 other than a defective CPS?


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

Error codes p0442 and po445


Po442 is evap system leak
check intake and all vacuum hoses for leaks
check evap canister and purge valve
Po445 is evap canister purge valve short circuit
check wiring and connection

Iscv 33


There is a digital stepper motor installed in the idle air control valve and it is operated by the ecm after taking all the outputs from various sensors.
Check engine light error code 33. The idle air control valve circuit open or shorted to ground. There could be three possibilities which can trigger this code and the check engine light comes on.
1. Check the wiring harness for open circuit or short to ground. Check the idle speed control valve connector for looseness,corrosion of poor contacts. Jiggle the harness at various places to find any damaged wire.
2. Idle speed control valve defective. (replace. Merely replacing the electronic part of the valve can also solve the problem)
3. ECM defective. (replace)

Code po320 speed sensor


Hi there:
Do a close visual inspection of the Crankshaft Position (CKP) sensor wiring and the terminals in the CKP sensor connector. Look for corroded or loose terminal connections, poor solder crimps, wiring insulation damage, intermittent shorts, etc...

If no problems are found during the visual inspection, replace the CKP sensor.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I keep getting a code P0340.Chrysler has reprogrammed the PCM for a long start issue.I cant seem to get anywhere with it.


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


Hope helps.

What is po411 and po445 for 2006 vw jetta/


P0411- Means Secondary Air Injection System Incorrect Flow Detected!
Possible causes - Vacuum hoses damaged.
- Air Pump inoperative.
- Air bypass solenoid circuit open.
- Air bypass solenoid leaking/blocked or stuck open/closed.
- Air diverter valve leaking/blocked or stuck open/closed.
- Air air hoses r Possible solution - Visually inspect vacuum lines for disconnects in the AIR systems and visually inspect for proper vacuum line routing. Repair if necessary.
- Disconnect the air pump hose at the solenoid valve, start the engine and see if there is air being pumped P0445- Means Evaporative Emission Control System Purge Control Valve Circuit Shorted! Possible causes - Damage harness or connectors to the Purge Control Valve
- The valve circuit is open or shorted
- EVAP canister purge volume control solenoid valve may be faulty
P0445 Description The EVAP canister purge volume control solenoid valve uses a ON/OFF duty to control the flow rate of fuel vapor from the EVAP canister. The EVAP canister purge volume control solenoid valve is moved by ON/OFF pulses from the ECM. The longer the ON pulse, the greater the amount of fuel vapor that will flow through the valve. When is the code detected? - An excessively high voltage signal is sent to ECM through the valve

OK, you have a code PO341 which means their is a problem with the signal the ECU is receiving from the cam sensor. It does not necessarily mean the sensor is bad. It can be one of these things.
1. Cam sensor wiring routed too close to spark plug wiring (causing interference) 2. Poor wiring connection at cam sensor 3. Poor wiring connection at PCM 4. Bad cam sensor 5. Damaged reluctor wheel You replaced the cam sensor and the problem is still there so we can assume that a defective cam sensor was not the problem. Do this.
1. Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.) 2. Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing 3. Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage 4. If reluctor isn't visible from outside the engine, visual test can only be done by removing cam shaft or intake manifold (depending on engine design)

Checking the fault codes


Yes.  Next to the ash tray there is a black slide off plate that reveals the OBD I plug.  {1996 and newer can be read with an OBD II reader (read for free at Advance auto or Auto Zone)}  Once you reveal this plug on the 1995, you can plug in a single jumper wire (or even a paper clip) in the #4 and #15 pin hole.  There are two rows of pin holes, count from the upper right to the #4, then on to #15 (which will be the second to last pin hole).  Turn the ignition switch on (motor not running), insert the jumper wire for about 3 to 5 seconds, then remove the wire.  The ENGINE LIGHT will flash a hold, then the code, which will go something like this, flash, flash, PAUSE, flash, flash, PAUSE, flash, PAUSE, flash, flash, flash, flash.  Then it will repeat the codes if you just sit there and observe it.  The code in my example would be a 2214 code.
Below are some code I found on a website.  I hope this helps.  Now I ask that you take the time to answer someone elses question.  Lets all share.  Good luck, "Peace through power and knowledge"
