P1336 Ford P1336 Ford - Crankshaft Position Or Camshaft Position Sensor Input Signal Error Share
0 ' Add Comment Possible causes
- Faulty Crankshaft Position Sensor
- Faulty Camshaft Position Sensor
- Crankshaft Position Sensor harness is open or shorted
- Crankshaft Position Sensor circuit poor electrical connection
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
What does this mean? When is the code detected?
The Engine Control Module (ECM) has detected a synchronization or signal error from the cam or crank sensors
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
- Engine difficult to start
P1336 Ford Description
The input signal to the powertrain control module (PCM) from the crankshaft position (CKP) sensor or the camshaft position (CMP) sensor is erratic.

What engine ? 2.9 - 3.7 - 4.8 - 5.3 L An do you mean- crankshaft position (CKP) sensor ? My GM service info shows only one on each of these engines ! What kind of problem are you having ? A no start - no spark ?

Consider replacing the crankshaft positioning sensor. A crank sensor is an electronic device used in an internal combustion engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters.
The simplest and most obvious symptom of a failing crankshaft position sensor is the blinking "check engine" light in your car.
According to Do It Yourself.com "When the crankshaft position sensor begins to fail, the signal it transmits to the vehicle's computer begins to weaken. If left unattended, the signal will switch off completely. This, in turn, causes the car's spark plugs to die out, killing the engine. If you are having problems starting your car, it could indicate bad crankshaft position sensor".

Of course this may NOT be YOUR problem, but it sounds like it could be, doesn't it?

This answer covers 1999-2005 Cadillac Deville, Eldorado & Seville.
Example Engine:
2002 Cadillac Seville STS 4.6L SFI DOHC HO 8cyl.

This engine has (2) Crankshaft Position (CKP) Sensors: the Upper sensor is CKP sensor B, and the lower sensor is CKP sensor A (this is included for the OBD-II DTC codes - P0385 references Sensor B = upper CKP sensor, whereas P0335 references the lower CKP sensor (sensor A)).

Both crankshaft position sensors are located in the front of the engine just above the oil filter adapter. To access both CKP sensors, jack up vehicle on the passenger side, remove the oil filter, and the oil filter adapter, including the Engine Oil Pressure (EOP) switch. See illustration.

The ARROW points toward Front of Car.
1. Upper Crankshaft Position Sensor (B).
2. Lower Crankshaft Position Sensor (A)
3. Engine Oil Pressure (EOP) switch
4. Engine Oil Level switch
The Oil Filter is the can-type object below the oil filter adapter, which includes the EOP switch. Recommend: remove oil filter with an oil filter socket/strap wrench, since it's close to the oil pan.

P1335 CHEVROLET P1335 CHEVROLET - Crankshaft Position Circuit Possible causes
- Faulty Crankshaft Position Sensor
- Crankshaft Position (CKP) Sensor harness is open or shorted
- Crankshaft Position (CKP) Sensor circuit poor electrical connection Help with this
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- Engine Stall
P1335 CHEVROLET Description
The Crankshaft Position (CKP) sensor sends pulses to the Powertrain Control Module (PCM) as the reluctor wheel teeth rotate past the CKP sensor. The PCM uses the CKP pulses to synchronize the ignition and fuel injector operation, and to time the interval between each CKP pulse. The PCM determines when an excessive change in crankshaft speed occurs by comparing each new time interval with the previous interval. A misfire causes an unexpected change in the crankshaft speed. A certain amount of acceleration/deceleration is expected between each firing stroke, but if the crankshaft speed changes more than an expected amount, the PCM interprets this as a misfire. The interval between CKP sensor pulses is extremely small. At high engine speeds, slight variations in the following components make misfire detection difficult:
- Crankshaft
- Reluctor wheel
- CKP sensor
The PCM learns variations during the Crankshaft Position System Variation Learning Procedure. The PCM compensates for these variations when performing detect misfire calculations. Only a scan tool can command the PCM to perform the Crankshaft Position System Variation Learning Procedure again.
Perform the learning procedure after the following actions:
- A PCM replacement
- Any operation or repair involving the crankshaft, the CKP sensor, or the CKP sensor to reluctor wheel gap relationship.
- An engine replacement.
- The ignition switch is in the ON position until the battery is drained.

P0336 Honda - Crankshaft Position Sensor 'A' Circuit Range/Performance

Possible causes
- Faulty crankshaft position sensor
- Crankshaft position sensor harness is open or shorted
- Crankshaft position sensor circuit poor electrical connection
- Signal plate may be damage
- Starter motor may be faulty
- Starting system circuit
- Dead or weak battery

crankshaft position sensor location for 3.3 V6 engine is mounted at the rear of the engine on transmission bellhousing, the 3.5 V6 engine crankshaft sensor located at front of the engine on the aluminum oil pan section below crankshaft pulley.replace the crankshaft position sensor remove heat shield disconnect the electrical connector the remove sensor retaining bolt then remove crankshaft sensor.after replacing crankshaft sensor you need to erase code if check light come back on.

P1345 is "Crankshaft position sensor / Camshaft position sensor correlation"

Code P1345 determines if the distributor is installed incorrectly, or if a mechanical malfunction is present in the engine. The light will trigger when the engine is running and the camshaft sensor reference pulse is not detected at a correct relative position with the crankshaft pulse. Most likely causes for this Chevy check engine light code include a faulty crankshaft position sensor, a wiring concern or an improperly installed distributor. A quick check on the crankshaft sensor is to monitor the RPM value with a scan tool while revving up the engine. If the reading is close to twice the expected RPM, then the sensor is likely faulty. There are other less likely concerns possible, such as base engine or computer related issues, but these involve more in depth testing. I hope this information is useful.

The check engine light doesn't have to come on with a bad crank sensor ,your vehicle has two , one for lower rpm an one for higher speeds . A&B
The two crankshaft sensors are located on the front bank (BANK 2) of the engine block between cylinders 4 and 6. Crankshaft position A sensor is located in the upper crankcase and crankshaft position B sensor is located in the lower crankcase. Both sensors extend into the crankcase and are sealed to the engine block with O-rings. The crankshaft position sensors are not adjustable.
