Typical Scan Tool DataEngine Speed
Circuit/System DescriptionThe 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 reading should be between 50-850 RPM. Circuit/System Testing
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. 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. Component TestingStatic Test
If not within the specified range, replace the B26 Crankshaft Position Sensor. If less than the specified value, replace the B26 Crankshaft Position Sensor. If less than the specified range, replace the B26 Crankshaft Position Sensor. Repair InstructionsPerform the Diagnostic Repair Verification after completing the diagnostic procedure. |
