Replace your camshaft sensor and check for a vacuum leak in your intake manifold, mostly towards the back. If you have a leak it will give false readings on your code reader. My truck was doing the same thing and we found the endcap on the maifold had blown off after a back-fire. We reglued the endcap and replaced crank and camshaft sensor and the truck runs better than it ever has!!! GOOD LUCK!!!!

Trying to find out where the crankshaft sensor is located on Mazda Tribute 2002? Need to change it


2004 Mazda tribute 2.0l manual transmission cranks position sensor tip worn / rubbing. p0351, p0352, p0500, p0320 codes. I have a 2004 Mazda tribute with 2.0l 4 cylinder. 140,000 miles. First problem was it would not start but I could hear the fuel pump run and the engine cranked over. I checked for spark and all four plugs had no spark. p0351, p0352, p0500, and p0320 codes displayed.
I have 12 volts at coil. I decided to remove and inspect crank sensor on the transmission side of the engine ( on engine below thermostat housing bolted to engine block) once i removed it i noticed the tip of the sensor was broken, yes, broken. so I knew i found the problem.
I put a new crank sensor in and the car started but ran for 1 hour idling as if a cylinder was not firing. Then it would not start ever again. I removed my brand new replacement sensor to find the tip was rubbed off enough to see the inside metal. i think it could be a possible warped flywheel but I am having trouble finding diagrams of the excitation part of how the crank position sensor works.
I believe the flywheel has holes that excite the sensor. The tribute does move and clutch works for the hour I had it running, so the manual Trans does work as well as the clutch.

Have you checked for a broken valve spring. Repaired a dodge engine with the same running issue as you have described and it was a broken intake valve spring.

98 wrangler shuts off and won't start intermittently. Codes are P1594, 0320, 0463 & 1391. Do I change the crank senor, cam sensor or fuel filter/regulator??


(this is for others who may be viewing this problem)
P1594 = charging system voltage is too high
P0320 = crankshaft position sensor (CKP)/engine speed (RPM) sensor-circuit malfunction
P0463 = fuel level sensor circuit, high output
P1391 = intermittent loss of CMP (camshaft position) or CKP (crank position) sensor

Probably start with changing the crank sensor. But keep in mind that the high charging system voltage may be causing the other electrical sensor problems. The voltage regulator (probably located internally in the alternator) is not regulating voltage properly. So changing the alternator may be needed as well. Price the parts and start with replacing the less expensive first.

Trouble code P0320 ignition/dist. engine speed input circuit


P0320 - Ignition / distributor engine speed circuit malfunction

The ignition engine speed sensor input signal to Powertrain Control Module (PCM) or Electronic Control Module (ECM) is continuously monitored. The test fails when the signal indicates that 2 successive erratic profile ignition pickup (PIP) pulses occurred.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- The engine may stumble or stall

When is the code detected?
The P0320 code is triggered when 2 successive erratic PIP pulses are detected.

Possible Causes:
- Loose wires/connectors
- Faulty Crank Position Sensors
- Arcing secondary ignition components (coil, wires and plugs)
- Low battery charge
- Powertrain Control Module

Possible Solutions:
- Resecure loose wire or connectors
- If battery charge is low, recharge or replaced battery
- Replaced crank position sensor
- Replaced starter motor


Test it and tell us news.

2002 Dodge Ram 1500 5.9 liter GAS not Diesel, giving code of p1391 which means cam/crank sensor - we have changed crank sensor and it's running worse - we have to start it about 3 times before it will quit...


most likely its the throttle body sludged up . clean the throttle body and butterfly . this will only help if there is an idling problem . ck for codes and ck freeze frame data for more help
