How Do You Reset Code P0012 on Ford F150?

The P0012 code in Ford F150 says, “A” Camshaft Place – Timing Over-Retarded (Financial institution 1).” Which means the camshaft place sensor detects that the engine’s timing is over-retarded on financial institution 1. Primarily, this code will get triggered by a defective VCT solenoid.

As well as, a broken cam phaser, defective wirings and a nasty timing belt may also set off this. With this code, you’ll expertise a lower in your truck’s efficiency.

What does the Code P0012 imply?

The P0012 code on Ford F150 means the camshaft has an issue with the VCT solenoid.

The camshaft place sensor has detected that the camshaft timing is off in relation to the crankshaft timing. Which means the camshaft is failing to open and shut on the acceptable time.

Though a defective VCT solenoid is the primary trigger for triggering the P0012 code, different causes exist, like a defective camshaft place sensor or a defective ECM. However these are extremely unlikely and uncommon circumstances.

How Critical is the P0012 Code?

The error code P0012 is a really severe situation, and it is best to attempt to repair the issue as quickly as attainable. Because the Ford F150 has an interference engine, relying on the mistiming, the valves, and pistons can collide with one another. This can trigger everlasting engine injury.

In a best-case situation, when you nonetheless drive with the P0012 code, your truck could have diminished gasoline effectivity, and the engine will make loud noises when accelerating.

This can make driving an disagreeable expertise for you and for the individuals round you.

Now that you just get the gist of the issue, let’s dig deep to search out the options.


The principle purpose for the P0012 code is a malfunctioning VCT solenoid. However the purpose for the malfunction could possibly be completely different. For instance-

  • Low, soiled, or fallacious engine oil.
  • Defective VCT solenoids
  • VCT solenoid circuit open or shorted
  • Camshaft phaser broken
  • Worn or cracked timing belt or chain 


P0012 Ford F150 signs are talked about below-

  • Verify the engine gentle on
  • Onerous beginning
  • Stalling
  • Tough idling
  • Loud engine noise when driving
  • Low gasoline effectivity
  • Low engine efficiency

Answer 1: Change the Oil

The very first thing it is advisable test is the engine oil. In case you’re utilizing the fallacious or contaminated oil, it could trigger the VCT solenoid to malfunction.

Ford recommends utilizing 5W-30 grade engine oil within the F150. Nevertheless, if you’d like the smoothest engine operation, it is best to use a full artificial 5W-30. For the engine oil high quality, here’s a video to test the quality-

Nevertheless, if that doesn’t work, let’s transfer on to the subsequent answer.

Answer 2: Verify and Substitute the VCT Solenoid

Listed below are the steps to test the VCT solenoid-

  • Find the VCT solenoids: The VCT solenoids are normally situated behind the oil filler tube and beneath the facility steering. However consult with the proprietor’s guide for affirmation. 
  • Disconnect the battery: Disconnect the unfavorable cable of the battery after which the constructive one. 
  • Take away the VCT solenoids: Take away the VCT solenoid on the driving force aspect, because the code signifies an issue solely with that one. However it’s essential to take away the air consumption pipe and energy steering reservoir to entry that.
  • Check the solenoid: Join the solenoids to a 12v battery utilizing alligator clips. The solenoids ought to make a clicking noise after connecting to the battery. Additionally, test the resistance of the solenoid utilizing a multimeter. The resistance must be between 5-15 ohms. 

If the VCT solenoid is just not working, change it with a brand new one.

Answer 3: Verify Continuity within the Wiring Harness

If the solenoids are okay, it’s essential to test their respective wiring harnesses. Use a multimeter to test the continuity of the wiring harness. This ensures energy to the solenoids.

If the connector doesn’t have continuity, you’ll have to change the wiring harness as effectively.

Answer 4: Verify the Camshaft Phaser

Subsequent, test the camshaft phaser. Verify the camshaft phaser for corrosion or injury. In that case, inspecting the VCT (variable camshaft timing) phaser indicator fingers on each the left and proper heads is advisable. The phaser ought to have a complete of 5 indicator fingers.

Beneath regular circumstances, the phaser sprocket ought to exhibit an “L” marking above its odd-numbered finger. 

An incorrect set up may be indicated by the phaser indicator’s odd finger on the precise aspect.

Conversely, the odd finger on the left aspect might point out particles lodged inside, resulting in inadequate rotation.

If that is so, you might have to disassemble the cam phaser to establish the underlying situation.

Here’s a video displaying the disassembly course of:

A corroded cam phaser may be cleaned utilizing baking soda and water. Unfold baking soda all around the corrosion, then use a small quantity of water to make a paste.

Depart the paste on the cam phaser for half-hour, then wash it off. If the cam phaser is broken, you have to to exchange it.

Answer 5: Verify the Timing Belt or Chain

If the cam phaser is just not the issue, a wrongly timed or broken timing belt/chain could also be the issue. The Ford F150s made after 2007 have a timing chain as an alternative of a belt.

Verify your timing belt or chain for injury. Additionally, test the timing of the engine. This video could also be helpful for figuring out in case your car’s timing is accurate-

Within the occasion of incorrect timing, re-time your engine. But when the timing belt or chain is broken, change it.

Learn how to Take Care of the VCT Solenoid in Ford F150

Common upkeep can forestall the P0012 code and maintain the VCT system wholesome in your Ford F150. Listed below are some tricks to preserve the VCT solenoids-

  • Use the proper engine oil: Utilizing the fallacious engine oil can injury the VCT solenoids and cam phasers.
  • Change your engine oil: Change and replenish your engine oil each 7,500 to 10,000 miles in case your engine makes use of full artificial engine oil. Usually the rule of thumb is to vary engine oil each 3,000 miles. 
  • Use OEM elements: If it is advisable change the cam phaser, timing belt/chain, or solenoids, at all times attempt to use OEM elements as an alternative of aftermarket ones.

Closing ideas

So, that’s all concerning the code P0012 in Ford F150. It is a fairly severe situation that requires speedy consideration, so do attempt to repair the issue as rapidly as attainable.

Nevertheless, if the analysis is past your talent stage, contact an knowledgeable or take your Ford F150 to a talented mechanic.
