Circuit/System Description

The crankshaft position sensor signal indicates the crankshaft speed and position. The crankshaft position sensor produces an alternating current voltage of different amplitude and frequency. The frequency depends on the velocity of the crankshaft, and the alternating current voltage output depends on the crankshaft position and battery voltage. The engine control module (ECM) can synchronize the ignition timing, fuel injector timing based on the crankshaft position sensor and the camshaft position sensor inputs. The sensor crankshaft position sensor is also used to detect misfire and tachometer display. The crankshaft position sensor circuits are connected directly to the ECM.

Conditions for Running the DTC

•  The engine is cranking or operating.
•  The engine control module detects no or wrong signal.
•  The DTC runs continuously once the above conditions are met.

Conditions for Setting the DTC

•  The engine is cranking or operating.
•  The engine control module detects no or wrong signal.
•  The DTC runs continuously once the above conditions are met.

Action Taken When the DTC Sets

DTC P0336 is a Type A DTC.

Conditions for Clearing the DTC

DTC P0336 is a Type A DTC.

Diagnostic Aids

The following conditions may also set the DTC:

•  Physical damage to the crankshaft position sensor or the reluctor wheel
•  Excessive play or looseness of the crankshaft position sensor or the reluctor wheel
•  Improper installation of the crankshaft position sensor or the reluctor wheel
•  Excessive air gap between crankshaft position sensor and the reluctor wheel

Circuit/System Verification

Engine starting or running, observe the scan tool Engine Speed parameter. The reading should be between 50-850 RPM.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the B26 Crankshaft Position Sensor.
2. Ignition ON, test for 2.0-3.0 V between the low signal circuit terminal 2 and ground.
⇒ If greater than the specified range, test the low signal circuit for a short to voltage. If the circuit tests normal, replace the K20 Engine Control Module.
⇒ If less than the specified range, test the low signal circuit for a short to ground or an open/high resistant. If the circuit tests normal, replace the K20 Engine Control Module.
3. Ignition ON, test for 2.0-3.0 V between the high signal circuit terminal 1 and ground.
⇒ If greater than the specified range, test the high signal circuit for a short to voltage. If the circuit tests normal, replace the K20 Engine Control Module.
⇒ If less than the specified range, test the high signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K20 Engine Control Module.
4. If all circuits test normal, test or replace the B26 Crankshaft Position Sensor.

Component Testing

Static Test

1. Ignition OFF, disconnect the harness connector at the B26 Crankshaft Position Sensor.
2. Test for 700-800 Ω between the high signal terminal 1 and the low signal circuit terminal 2.
⇒ If not within the specified range, replace the B26 Crankshaft Position Sensor.
3. Test for infinite resistance between each terminal and the sensor housing/case.
⇒ If less than the specified value, replace the B26 Crankshaft Position Sensor.
4. Engine cranking, test for greater than 0.5 V alternating current between the high signal circuit terminal 1 and the low signal terminal 2.
⇒ If less than the specified range, replace the B26 Crankshaft Position Sensor.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.

•  Engine Control Module Replacement for ECM replacement, setup, and programming
