P1004-SHORT RUNNER VALVE CONTROL PERFORMANCE

• When Monitored:

With the engine run time above a calibrated value, battery voltage greater than 10.4 volts , ECT within a specific range, and the Short Runner Valve Assembly control active.

• Set Condition:

This PCM compares the circuit feedback to a calibrated closed range when the circuit is de-energized or to a calibrated open range when the circuit is energized. If the value is determined to be out of the calibrated range in either the de-energized or energized state for more than a calibrated amount of time, this DTC will set.

No

• Go to 6

6. POWERTRAIN CONTROL MODULE (PCM)

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Short Runner Valve Assembly and the Powertrain Control Module (PCM).
Look for any chafed, pierced, pinched, or partially broken wires.
Look for broken, bent, pushed out or corroded terminals.
Refer to any Technical Service Bulletins that may apply.

Were any problems found?

Yes

• Repair as necessary.
• Perform the PCM Verification Test. See: Verification Tests\PCM Verification Test

No

• Replace and program the Powertrain Control Module (PCM).
• Perform the PCM Verification Test. See: Verification Tests\PCM Verification Test
