P0012 says the cam shaft signal is over retarded on bank 1, P0021 says that the cam shaft timing on bank 2 is over advanced. P0345 and P0349 means your cam shaft sensor cannot be read. Finally cylinder 7 (P0307) has a misfire. Changing your camshaft sensor would be a good start and then have the codes cleared. Switching the car on and off 5 times or disconnecting the battery negative terminal for 10 minutes will often clear the codes. With any luck everything will be resolved by the new cam shaft sensor. If the misfire is still present remove the spark plug and inspect it. If the plug is OK check out the HT lead and connection to see if there are any shorts.

P0012 and p0021 tells me you haven't payed much attention to your oil and that the valve timing solenoids got stuck. the sensors probably are still good. also check your chain and guides they might be worn. and prepare for the worst spark plug situation imaginable. they will brake into 4 pieces and you will need to buy a special tool to pull out the parts. so replace them with champion plug 7989 (double platnum one piece) superior to the motorcraft 2 piece problem. and don't forget to anti-seize the threds.

How to fix fault p0021 and engine failsafe program


(powertrain control module, also called an ECM). That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.
Symptoms Possible sumptoms of OBD code P0021
Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes Possible causes of OBD code P0021
A P0021 DTC trouble code may be caused by one or more of the following:
Possible Solutions This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

P0345 and p0349


Since you didn't post the engine size, or the year, I am taking a stab at your year, which the codes cover several:

P0345-Camshaft position sensor A circuit

P0349-Camshaft position sensor A circuit intermittent

Check the harness to the sensor for any damage, scrapes, dents...something in your harness may be causing the intermittent fault to log in.

Fault code P0021


Hi there:P0021 - "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2)

A code P0021 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0021 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. A P0021 engine code is basically the same as a P0011 code, except this is for Bank 2, not Bank 1.

Most likely a P0021 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.


A P0021 DTC trouble code may be caused by one or more of the following:Incorrect camshaft timingWiring problems (harness/wiring) in intake timing control valve control solenoid systemContinuous oil flow to VCT piston chamberFailed timing valve control solenoid (stuck open)

Possible Solutions:This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.To reset the fuel pump, press the button on the switch. The switch is located immediately below the hole in the trunk side trim.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.


Thank you for using FixYa.

P0012


P0012 - "A" Camshaft Position - Timing Over-******** (Bank 1)
OBD-II DTC Trouble Code Description

"A" Camshaft Position - Timing Over-******** (Bank 1)
What does that mean?

A code P0012 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0012 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-********, the engine light will be illluminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft.
Potential Symptoms

Most likely a P0012 DTC will result in one of the following:

hard starting
poor idle and/or
stalling

There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.
Causes

A P0012 DTC trouble code may be caused by one or more of the following:

Incorrect camshaft timing
Wiring problems (harness/wiring) in intake timing control valve control solenoid system
Continuous oil flow to VCT piston chamber
Failed timing valve control solenoid (stuck open)

Possible Solutions

The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

P0012 Intake camshaft position timing over retarded bank one Is this a easy fix


Code P0012 - Variable Camshaft Timing Over Retarded - Bank 1

How does a P0012 code trigger the check engine light? This code will trigger the check engine light under the following condition:
* The comprehensive component monitor, referred to as the CCM, monitors the Variable Camshaft Timing (VCT) position for over-retarded cam timing. If the cam timing exceeds a maximum calibrated limit or is stuck in a retarded position, the check engine light will come on and set this trouble code.

Possible Causes:
Incorrect camshaft timing
VCT solenoid valve stuck open or continuous oil flow to piston chamber
Camshaft advance mechanism binding, or faulty VCT unit

Diagnostic Help:
This check engine light code is caused by a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis. Possible symptoms may include rough idle, stall or hard start. Refer to manufacturer specific component tests for the VCT unit. You may also use the "Get Help" link if you need specifications or have any other related questions. Remember to refer to an appropriate manual for specific instructions.

Other details mentioned a P0012 DTC trouble code may be caused by one or more of the following:
* Incorrect camshaft timing
* Wiring problems (harness/wiring) in intake timing control valve control solenoid system
* Continuous oil flow to VCT piston chamber
* Failed timing valve control solenoid (stuck open)

Possible Solutions:
The main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit. Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

My ODB-ll code reader displays P0345 and P0349 what is the difference between each one .i replaced both camshaft position sensors


The difference between the two is,
P0345--- there's a problem in the camshaft position sensor "A" circuit on bank 2,
P0349--- it's an intermitten problem in the camshaft position sensor "A" circuit on bank 2, which means the problem comes and goes.
