How to Reprogram Ford PCM ECM reflash

On this vehicle I was unable to find any On this vehicle I was unable to find any visible leaks with a smoke machine but was able to find a possible cause and in this video I show you how to easily remedy that thanks for watching be sure to subscribe to the flat rate mechanic for more money-saving auto repair videos.

1. Monitor the fuel tank pressure sensor voltage either with the scanner or using at voltmeter (Green/Orange wire pin 33 at the Electronic Control Module). The fuel tank pressure sensor should have approximately 5 volts on the Red wire (pin 44) and a ground on the Blue/Black wire. With atmospheric pressure on the system, the voltage on the Green/Orange wire should be near 2.5 volts.

2. Next ground the canister close valve Blue/Black wire, this should close the valve and seal the system.

3. With the engine idling, locate the purge control valve (under the throttle body, inline of the vacuum hose) and tap the Yellow/Orange wire to ground while watching the fuel tank pressure sensor voltage. Bring the voltage down to near 1 volt and stop tapping the ground. The voltage should hold if there are no leaks. If the voltage starts to rise pinch off the hose between the canister and the fuel tank. If the voltage stops rising the leak is in the canister, canister close valve or hoses.

BMW P0014 P0015 Intake Exhaust valve timing “Try This First”

by
bmw p0015 p0014

2007 BMW X3 3.0SI 3.0L, L6
Customer Concern: Check engine light is on.
Tests/Procedures: 1. Check for sludging of oil and lack of oil changes during the vehicle history.

VVT Solenoid: https://amzn.to/2IczM7N
Pocket Code Reader: https://amzn.to/2DZpdCM
Power Probe tester: http://amzn.to/2FN2r70

Sludging of the oil and burnt oil can lead to the camshafts not being able to adjust as commanded by the engine control module. Oil pressure is controlled by solenoids mounted on the engine near the camshafts. Poor flow and lack of oil pressure will cause slow or no movement of the camshaft timing mechanism.

2. Check the solenoids themselves for power at one of the wires to the solenoid. Ground the other wire at the solenoid and the solenoid should click. If not, the solenoid is faulty. Different codes should be set for faulty solenoids, but it should be verified anyway.

3. Remove the solenoids and look at the oil or lack of oil, that comes out of the solenoids when removed. If gummed up and burnt, oil supply could be an issue.

4. Incorrect timing of the engine can also lead to this code being set. If the engine was recently disassembled and the proper tools were not used for camshaft timing, the engine will need to be set up properly.
Tech Tips: Both fault codes relate to incorrect camshaft timing or camshaft timing control problems.
