My pt cruiser has code 1391. i changed cam sensor crank sensor wires plugs and coil still getting 1391 code and from 0 mph to 20 mph car skips and revs up any ideas?


The cam and crank sensors have the same power wire. Go after that one. They also have the same ground, but other sensors connect to it also. So it's not the ground. And they have separate return signal wires. Not them either.

2001 jetta vr6 cranks but won't start have fuel and spark replaced camshaft sensor, new plugs valve cover gasket got code of PO343 and PO740


code po740 refers to torque converter clutch(TCC) solenoid-circuit malfunction==causes --wiring--TCC solenoid-ECM/TCM
code p0343 refers to cam shaft position sensor(CMP) A bank1-high input.==causes --wiring short to positive--CMP sensor---ECM. check which cam sensor you replaced and check the wiring connectors. use a code reader to reset the cpu when finished

My 1991 oldsmobile eighty eight royale keeps dying when i drive it, I have replaced ing control moduel, fuel pump, mass air flow , cam shaft sensor, timing chain, plugs wires ect. do i need to keep...


With that much already invested, why give up now? How about the crank position sensor-was that replaced as well? For spark control and spark timing, the computer needs inputs from both the cam position sensor and the crank position sensor before it can know when to cut power to the coils for spark to occur.
Before proceeding any further, you should check for diagnostic trouble codes. You would need an OBD 1 type code reader or scanner for your olds. Any stored codes may help you find the problem.
You can test the ignition system by checking for spark on a spark plug wire when the engine is cranking over. Pull the plug wire off a spark plug and put in a clean spark plug into the wire. Lay the plug so the threads are touching metal on the engine somewhere. Have someone crank the engine over and watch for a spark from the spark plug. If you have a blue, snapping spark when cranking, ignition is good.
One last note: since it dies when driving, there is a possibility that you have a malfunction in the pcm-the computer.

P0341 - Camshaft Position Sensor Circuit Range/Performance

This P0341 code basically means that the powertrain control module (PCM) detected a problem with the camshaft signal. The camshaft position sensor (CPS) sends a specific signal to the PCM for Top Dead Center on the compression stroke as well as signals indicating the position of the cam sensor. This is accomplished through a reluctor wheel attached to the camshaft that passes by the cam sensor. Any time that the signal to the PCM is inconsistent with what the signal should be, this code is set. NOTE: this code can also be set by extended cranking periods.

Symptoms: The car will likely run with this code set, as it is often intermittent and also because the PCM can often operate the vehicle in "limp-in/limp-home" mode even with a cam sensor signal problem. There may be no noticeable symptoms other than:
* Poor fuel economy (if engine runs)
* Possible no start condition


Causes: A code P0341 may mean that one or more of the following has happened:
* Cam sensor wiring routed too close to spark plug wiring (causing interference)
* Poor wiring connection at cam sensor
* Poor wiring connection at PCM
* Bad cam sensor
* Damaged reluctor wheel

Possible Solutions: Often relacing the sensor fixes this code, but not necessarily. Therefore it's important to check the following:
* Check that the wiring isn't routed too close to any secondary ignition components (coil, spark plug wires, etc.)
* Visually inspect the wiring at the sensor for any burn marks, discoloration indicative of melting or chafing
* Visually inspect the cam sensor for damage
* Visually inspect the reluctor wheel through the cam sensor port (if possible) for any missing teeth or any damage
* 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)
* If all checks out okay, then replace the sensor.

1993 subaru legacy (non-turbo). I am not getting a spark. I replaced the plugs, wires, coil, cam sensor, and crank sensor. The car will turn over but not start. I checked the codes via service engine soon...


check 2 see if you have power going 2 your cam and crank sensors. if you do make shure the wires havnt poped out a bit... if you have no power there you will have 2 trace the wiring too see if there is a lose connection...
