P2851 Possible Causes

• Outdated Transmission Control Module (TCM) programming (reprogram TCM)
• Faulty Transmission Control Module (TCM)
• Defective transmission assembly

How to Fix P2851 Code

Check 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.

Possible Symptoms

Check engine light illuminated (or service engine soon warning light)

P2851 Meaning

There are two electric motors used for shifting gears in the transmission, one for gears 1-3-5 and one for gears R-2-4-6. The gear shift is performed by two shift drums connected to the shift motor pinion via two ideal gears. The maximum shifting force is 1500 N (337 lb). The motors are integrated into the Transmission Control Module (TCM) and operate independently of each other.

P2841 Possible Causes

• Outdated Transmission Control Module (TCM) programming (reprogram TCM)
• Faulty Transmission Control Module (TCM)
• Defective transmission assembly

How to Fix P2841 Code

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

P10E6 Possible Causes

• Faulty Valvetronic actuator motor
• Valvetronic actuator motor wiring harness open or shorted
• Valvetronic servo motor poor electrical connection in motor circuit

How to Fix Code P10E6

Check 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.

Possible Symptoms

Engine light on (or service engine soon warning light)

P10E6 Meaning

The Engine Control Module (ECM) monitors the Valvetronic actuator motor. The ECM sets the OBDII code when the Valvetronic actuator motor does not meet factory specifications.

P1001 2001 FORD F150 Possible Causes

• Incorrect self-test procedure
• Unexpected response from self-test monitors
• RPM out of specifications

P1002 Possible Causes

• Faulty ignition switch
• Ignition switch harness is open or short-circuited
• Poor electrical connection in ignition switch circuit
• Faulty Body Control Module (BCM)

P1003 Possible Causes

• Faulty EFI system relay
• EFI system relay wiring harness is open or short-circuited
• Poor electrical connection in EFI system relay circuit

P1004 Possible Causes

• Faulty short runner valve assembly
• Short runner valve circuit open or shorted
• Poor electrical connection in short runner valve circuit
• Faulty Powertrain Control Module (PCM)

How is P1004 Code Repaired?

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.

When is the Code Detected?

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.

Possible Symptoms

Illuminated engine light (or service engine soon warning light)

P1004 Meaning

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.

P1004 BMW Causes

• Faulty Valvetronic eccentric shaft sensor
• Valvetronic eccentric shaft sensor wiring harness open or short-circuited
• Poor electrical connection in Valvetronic eccentric shaft sensor circuit
• Missing reluctor on Valvetronic eccentric shaft sensor

How is BMW P1004 Code Repaired?

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.

When is the Code Detected?

Valvetronic eccentric shaft guiding sensor solenoid loss bank 1

Symptoms

Possible

Engine light on (or service engine soon warning light)

P1004 BMW Meaning

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.

P1004 CHRYSLER Possible Causes

• Faulty Short Runner Valve assembly
• Short runner valve circuit open or shorted
• Poor electrical connection in the short runner valve circuit
• Faulty Powertrain Control Module (PCM)
