P0336 - Crankshaft Position Sensor A Circuit Range/Performance

4-58 Powertrain DTC Charts and Descriptions

Diagnostic Trouble Code (DTC) Charts and Descriptions

P0336 - Crankshaft Position Sensor A Circuit Range/Performance (Continued)

Diagnostic Aids: An inactive CKP signal causes a no start condition. Monitor the RPM PID while cranking the engine. A value of

0 RPM indicates a CKP concern.

P0339 - Crankshaft Position Sensor A Circuit Intermittent

Description: This DTC sets when several erratic profile ignition pickup (PIP) pulses have occurred in the crankshaft position

(CKP) sensor signal within a calibrated time period when the camshaft speed exceeds the equivalent speed of engine idle or the starter motor is engaged.

Possible Causes: • CKP+ circuit intermittent open (VR type)

• CKP- circuit intermittent open (VR type)

• CKP circuit intermittent open (Hall effect type)

• VREF circuit intermittent open (Hall effect type)

• SIGRTN circuit intermittent open (Hall effect type)

• CKP+ circuit intermittent short to voltage (VR type)

• CKP- circuit intermittent short to voltage (VR type)

• CKP circuit intermittent short to voltage (Hall effect type)

• VREF circuit intermittent short to voltage (Hall effect type)

• SIGRTN circuit intermittent short to voltage (Hall effect type)

• CKP+ circuit intermittent short to ground (VR type)

• CKP- circuit intermittent short to ground (VR type)

• CKP circuit intermittent short to ground (Hall effect type)

• VREF circuit intermittent short to ground (Hall effect type)

• SIGRTN circuit intermittent short to ground (Hall effect type)

• CKP sensor incorrectly installed

• Damaged CKP sensor

• Incorrect, damaged or corroded connections

• Arcing secondary ignition components (coil, wires and plugs)

• Arcing relays or other high current devices (cooling fan or starter motor)

• On board 2 way radio transceiver

• Radio frequency interference or electromagnetic interference from an external source

• Improperly grounded high power aftermarket equipment

P0340 - Camshaft Position Sensor A Circuit (Bank 1 Or Single Sensor)

Description: This DTC sets when the CMP11 circuit signal cannot be detected. For additional camshaft position (CMP)

sensor location information, refer to Section 1, Engine Control Components.

Possible Causes: • CMP11 circuit open

• CMP11 circuit short to ground

• CMP11 circuit short to voltage

• SIGRTN circuit open

• VRSRTN circuit open

• CMP11 circuit shorted to other CMP circuits (2 or more CMP sensor systems)

• Camshaft timing incorrectly set

• Camshaft position sensor trigger wheel out of alignment

• Damaged camshaft position bank 1 sensor 1 (CMP11) shielding

• CMP11 sensor incorrectly installed

• Damaged CMP11 sensor

Diagnostic Aids: Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have

an intermittent impact on the CMP signal.
