SOURCE: have code p1391 and p0340, replaced both sensors

had similar problem with 99 ram. i made holes in crank sensor a bit bigger,removed rubber seal that sensor goes through in trans,installed 1 bolt and adjusted sensor back towards firewall and tightened that 1 bolt and its worked fine ever since

SOURCE: 1999 dodge caravan new pcm new crank and cam

If you have replace new cam sensor with no sparks and the coil are good putting out 12 volt, my guess would be the computer it self faulty. cam sensor sense the cam turning and send info to computer telling computer to disperse the charge from the coil pack to the plugs assuming relay, cam sensor, coil, plugs, and wires are good. make sure the cam sensor is put in properly and position.

SOURCE: code reads P0340 Camshaft position Sensor circuit

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.

My 95 Jeep Grand Cherokee keeps shutting off while driving. Sometimes I can put it in neutral and restart the engine while rolling. Most times, not. After 5-10 minuets and as many times cranking, it will...


54 - Sync Pick-Up Signal Not Detected (Camshaft Position Sensor/Ignition Pickup). recheck to see if power to sensor. make sure wire is in good shape, to cam sensor. 11 - No Crank Reference Signal At Power control module, crank shaft sensor. check to see if your getting signal from pcm. Good-day!

PCM= Powertrain Control Module. It is the brains of the car, it reads the sensor in put from all sensors including the cam shaft position sensor

So... I'm starting to get just a bit frustrated... after installing the new PCM, my dodge avenger, 96 2.0L ran for 5 days then went out again, fuel pump works and I've got spark but no start..


after all that work its terrible that something else goes bad however since you do get spark and fuel i would say crank or cam sensor but then if one of those goes bad it wont allow engine to turn over and would shut fuel pump off. so there is only one thing left to cause it you have a short in the harness somewhere maybe just a lose connection on the cam or crank sensor put dieelectric grease in all your connectors

Hi there:

P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.



The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.



Causes may include:
Timing chain stretched, or timing belt skipped a tooth due to wear
Misalignment of timing belt/chain
Tone ring on crankshaft slipped/broken
Tone ring on camshaft slipped/broken
Bad crank sensor
Bad cam sensor
Damaged wiring to crank/cam sensor
Timing belt/chain tensioner damaged

Possible Solutions: First, visually inspect the cam and crank sensors and their harnesses for damage. If you notice broken/frayed wires, repair and recheck.
If you have access to a scope, check the cam and crank patterns. If a pattern is missing, suspect a bad sensor or a slipping tone ring. Remove the cam gear and the crankshaft harmonic balancer and inspect the tone rings for proper alignment and make sure they're not loose or damaged or that they haven't sheared the key that aligns them. If they are properly installed, replace the sensor.
If the signal appears normal, then check the timing chain/belt for proper alignment. If it's misaligned, check for a damaged tensioner that may have allowed the chain/belt to slip a tooth or several teeth. Also check that the belt/chain isn't stretched. Repair and recheck.

Other crank sensor codes include P0017, P0018, P0019, P0335, P0336, P0337, P0338, P0339, P0385, P0386, P0387, P0388, and P0389.

Where is the thorttleposition sensor on 2001jeep cherokee


The 3 wire Throttle Position Sensor (TPS) is mounted on the throttle body and is connected to the throttle blade.
The TPS is a 3wire variable resistor that provides the Powertrain Control Module (PCM) with an input signal (voltage) that represents the throttle blade position of the throttle body. The sensor is connected to the throttle blade shaft. As the position of the throttle blade changes, the resistance (output voltage) of the TPS changes.
The PCM supplies approximately 5 volts to the TPS. The TPS output voltage (input signal to the PCM) represents the throttle blade position. The PCM receives an input signal voltage from the TPS. This will vary in an approximate range of from .26 volts at minimum throttle opening (idle), to 4.49 volts at wide-open throttle. Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:

Along with inputs from other sensors, the PCM uses the TPS input to determine current engine operating conditions. In response to engine operating conditions, the PCM will adjust fuel injector pulse width and ignition timing.
The PCM needs to identify the actions and position of the throttle blade at all times. This information is needed to assist in performing the following calculations:


Ignition timing advance Fuel injection pulse-width Idle (learned value or minimum TPS) Off-idle (0.06 volt) Wide Open Throttle (WOT) open loop (2.608 volts above learned idle voltage) Deceleration fuel lean out Fuel cutoff during cranking at WOT (2.608 volts above learned idle voltage) A/C WOT cutoff (certain automatic transmissions only)


Removal & Installation

3.7L & 4.0L

  1. Disconnect TPS electrical connector.
  2. Remove TPS mounting screws.
  3. Remove TPS.

To Install:
The TPS is mounted to the throttle body. The throttle shaft end of throttle body slides into a socket in the TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.
  1. Install TPS and retaining screws.
  2. Tighten screws to 7 Nm (60 inch lbs.) torque.
  3. Connect TPS electrical connector to TPS.
  4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.

4.7L
  1. Remove air duct and air resonator box at throttle body.
  2. Disconnect TPS electrical connector.
  3. Remove two TPS mounting bolts (screws).
  4. Remove TPS from throttle body.

To Install:
The throttle shaft end of throttle body slides into a socket in TPS. The TPS must be installed so that it can be rotated a few degrees. If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs. The TPS will be under slight tension when rotated.
  1. Install TPS and two retaining bolts.
  2. Tighten bolts to 7 Nm (60 inch lbs.) torque.
  3. Manually operate throttle control lever by hand to check for any binding of TPS.
  4. Connect TPS electrical connector to TPS.
  5. Install air duct/air box to throttle body.

Hope this helps

1. Monitor the 5v reference, Gray wire to the Throttle Position Sensor (TPS) with a Digital Volt Ohm Meter (DVOM) set to the MIN/MAX setting.

2. Monitor the TPS signal circuit, Blue wire with a DVOM. Voltage should range smoothly from approximately 0.44 to 5.0 volts as the throttle is opened.

3. Tap test the Electronic Control Module (ECM) and see if the codes come back or if the engine reacts.

I have a 2000 dodge durango, I have a code P0320.


I put in a new crank positioning sensor and it fixed my problem. 42.00 dollars from NAPA. took about 2 hours to change it.
