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
DTCs P0335 or P0336 are Type A DTC.
Conditions for Clearing the DTC
DTCs P0335 or P0336 are 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. |
Test for less than 5 Ω
of resistance between the low reference circuit terminal 2 and
ground. |
| ⇒ |
If greater than the specified range, test the low
reference circuit for an open/high resistant. If the circuit tests
normal, replace the K20 Engine Control Module. |
| 3. |
Ignition ON, test for greater
than 4.8 V between the 5 V reference circuit terminal 3 and
ground. |
| ⇒ |
If less than the specified range, test the 5 V
reference circuit for a short to ground or an open/high resistance.
If the circuit tests normal, replace the K20 Engine Control
Module. |
| 4. |
Ignition ON, test for 4.8-5.2
V between the signal circuit terminal 1 and ground. |
| ⇒ |
If less than the specified range, test the signal
circuit for a short to ground or an open/high resistance. If the
circuit tests normal, replace the K20 Engine Control Module. |
| ⇒ |
If greater than the specified range, test the
signal circuit for a short to voltage. If the circuit tests normal,
replace the K20 Engine Control Module. |
| 5. |
If all circuits test normal,
test or replace the B26 Crankshaft Position Sensor. |
Repair Instructions
Perform the
Diagnostic Repair Verification after completing the diagnostic
procedure.
