SOURCE: I can't find crankshaft sensor, am I looking in right place!

If the engine is a 2.4L four cylinder engine, the crankshaft position sensor is located on the engine, passenger side, where the crankshaft comes out of the engine, on the lower side. You can see the sensor from the top side, with a 2 point wire connector on it. Just disconnect the wire, and use a deep socket to remove the sensor from the engine. It should come out without spilling any oil, and if you have a new sensor available, be sure to match the O-ring on the old sensor, then lubricate the O-ring with oil, and push the new sensor in, bolt it down, reconnect the wire, and the job is done.

SOURCE: Car will not start.Engine turns over but spark plugs willnot fire

I would say replace ignition coil, that might me the problem, otherwise it can be the ecu, which might have some electrical problems not allowing the car to stay running. Good luck.

SOURCE: I have a 94 S10

if no crank sensor by timing cover, some vehicles are controlled at the distributor. the 95-96 have sensor by cover . before 1995 this its controlled by distributor. there is no "crank sensor" on that engine the pick-up coil inside the distributor acts as the crank reference for that engine. have a good day !! 4.3 vortex engine.

Camry engine shuts down


code p3190 refers to low engine power--malfunction. Possible causes ---intake system, fuel system---mechanical fault---Mass air flow sensor---engine coolant temperature sensor---crankshaft position sensor---camshaft position sensor --- ECM. I would start with the water coolant sensor as if it reads boiling it will shut down the engine.

I changed the harmonnic ballancer and the sensor and got code p0336 didnt have this code untill I had to change harmonic.


P0336 Crankshaft Position Sensor A Circuit Range/Performance.

Potential causes of a P0336 code include:

  • Bad crank sensor
  • Broken reluctor ring (missing teeth, debris lodged in ring)
  • Reluctor ring dislodged/stripped from it's stationary location
  • Wiring harness chafing causing short
  • Wiring open in CKP circuit, good-day ! CKP=crankshaft position sensor. The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Electronic Control Module(ECM) to control ignition and fuel injection. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. good-day !

Where does the cam position sencer located at


It's officially called a CMP Syncronizer.
There are stern warnings on the page associated with this.
CAMSHAFT POSITION (CMP) SENSOR Removal & Installation
CMP sensor is located on rear of engine, behind intake manifold. Before removing, note position of electrical connector on CMP sensor. Remove upper intake manifold. See UPPER INTAKE MANIFOLD . Disconnect CMP sensor. Remove CMP sensor screws and CMP sensor. To install, reverse removal procedure. Ensure CMP sensor electrical connector is pointing in original direction. Tighten CMP sensor to specification.
2 . Failure to use synchro positioner during installation will cause fuel injection to be out of time and may cause engine damage.
CAUTION: DO NOT rotate crankshaft when Synchro Positioner (T95T-12200-A) is positioned on CMP synchronizer. Armature tab will be damaged and synchronizer timing may be shifted. Removal
1. Position crankshaft to TDC of cylinder No. 1, on compression stroke. Note position of electrical connector on CMP sensor. 2. Disconnect negative battery cable. Unplug harness connector from CMP sensor. Remove CMP sensor screws and CMP sensor from positioner. Remove synchronizer hold-down bolt and CMP synchronizer.
Fig. 2: Exploded View Of CMP Synchronizer Assembly (Typical) Courtesy of FORD MOTOR CO.
CAUTION: DO NOT rotate crankshaft while synchronizer is removed from engine. Installation
1. Install Synchro Positioner (T95T-12200-A) on synchronizer housing. See Fig. 3 . Rotate synchronizer shaft until vane on shaft aligns with slot on synchro positioner. Rotate synchro positioner until engaged into notch in housing. Dip drive gear in engine oil.
Fig. 3: Installing Synchro Positioner On Synchronizer Assembly (Typical) Courtesy of FORD MOTOR CO.
Fig. 4: Positioning Synchronizer For Installation Courtesy of FORD MOTOR CO. 2. Rotate sychronizer assembly so that synchro positioner is 60 degrees counterclockwise of crankshaft centerline before inserting synchronizer assembly into engine. See Fig. 4 . 3. As synchronizer is inserted into engine, synchronizer will rotate. When seated, synchronizer electrical connector should be located in original position.
CAUTION: If CMP sensor electrical connector is not positioned correctly, DO NOT reposition connector by rotating synchronizer. This may cause fuel system to be out of time with the engine, causing possible engine damage or an engine misfire. Remove synchronizer and reinstall. See step 3 . 4. Install hold-down clamp and tighten bolt to specification. See TORQUE SPECIFICATIONS . Install CMP sensor to synchronizer and tighten to specification. Ensure CMP sensor electrical connector is in original position. Reconnect wiring to CMP sensor. Connect negative battery cable.

Check the Camshaft Position Sensor or the Crankshaft Position Sensor. Those are the modern day Distributor Caps of the 21st Century, if neither of them are working the ECM (Computer) does not know what position the Crankshaft is in so it will not be able to start your motor.,

No reverse only drives for 30 seconds limp mode???? please help!


P1388 = Auto Shutdown (ASD) relay control circuit open or shorted.
The ASD relay routes battery power to the ignition coils, and is energized by the PCM as long as it receives signals from both the crankshaft and camshaft position sensors. If the engine stops turning (stalls), the PCM deengerizes the ASD relay and shuts down the ignition system. The ASD relay also supplies battery voltage to the fuel injectors, so when it shuts down it cuts off both ignition and fuel. At the same time, the PCM also deenergizes the fuel pump relay to turn off the fuel pump. For "limp in" capability, the Chrysler system can run with input from the crankshaft position sensor only. The ASD and fuel pump relays are both located in the Power Distribution Center.

Crankshaft position sensor replaced and car shuts off


Hello, The crankshaft sensor is located at the left rear of the motor, behind the left cylinder head where the transmission bolts up. I believe that it has a 6mm allen head screw holding it down.
I hope this helps.

On the 1999 - 2000 5.7 vortec engines the distributor gears wear causing the timing to change 2 or more degrees. The ecm is designed to shut down at 2 or more degreedifference. This is in a GM bulletin that recommends replacement at 160k miles. Mine went out at 150k miles. Very similar driving symtoms until it quit running. Both cam sensor codes were set on mine though, not the crank sensor.
