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.

Under crankshaft pulley.

ITS LOCATED NEXT TO THE CRANKSHAFT PULLEY . ITS A SIMPLE MATTER OF TAKING OUT THE OLD AND PUTTING IN THE NEW.

Your talking about an astro van right? If so the timing is not adjustable. It is set by the computer, using various sensors, like the crankshaft position sensor, the throttle position sensor and others.

It mounts in the side of the block near the crankshaft,it fits in a hole,going into the engine block.,look on the inside of the engine compartment ,on the firewall side,left of the pulleys,down low.

CKP SENSOR IS LOCATED BEHIND STARTER IF ITS NOT BEHIND STARTER LOOK AROUND CRANKSHAFT PULLEY. YOU HAVE TO REMOVE STARTER TO GET TO IT IF IT LOCATED THERE.

The Crankshaft Position Sensor is located under hood, center, rear engine area, below ingnition coil pack and DIS module, mounted in engine block.

Crankshaft Position (CKP) Sensor
A magnetic crankshaft sensor (Hall Effect switch) is used which is remotely mounted on the opposite side of the engine from the DIS/IC module. The sensor protrudes in to the engine block, within about 0.050 in. (1.27mm) of the crankshaft reluctor.

I really hope help you wuth this (rated this help). have a nice day, good luck.
