P1001 2001 FORD F150 Possible Causes
P1002 Possible Causes
Begin by checking the “Possible Causes” listed above. Visually inspect the wiring harness and related connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.
The P1004 code is detected when it’s determined that the value is outside the calibrated range in the power-off operating cycle, greater than 85% or less than 75%, or during power-on, greater than 55% or less than 35% duty cycle, condition lasting more than a calibrated duration, this DTC will be set.
Illuminated engine light (or service engine soon warning light)
The SRV (Short Runner Valve) system is used to improve engine performance. The SRV system allows intake boost air to bypass the long runners of the intake manifold between the intake manifold plenum and the intake manifold to cylinder head interface by providing a shorter runner directly between the plenum and cylinder head interface. The SRV position is controlled by a pneumatic/spring actuator and electronic solenoid valve. The Powertrain Control Module (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.
Start by checking the “possible causes” listed above. Visually inspect the wiring harness and associated connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible
Engine light on (or service engine soon warning light)
The Engine Control Module (ECM) monitors the Valvetronic eccentric shaft sensor. The ECM sets the OBDII code when the Valvetronic eccentric shaft sensor does not meet factory specifications.

The SRV (Short Runner Valve) system is used to improve engine performance. The SRV system allows intake boost air to bypass the long runner slides of the intake manifold between the intake manifold plenum and the intake manifold to cylinder head interface by providing a shorter runner directly between the plenum and cylinder head interface.
