2003 trouble code P0012 Miata

Mustgo has a reasonable fix for this problem posted here(it was a 2001 Miata instead of a 2003). Code means timing is retarded. Bad cam sensor seems correct.
My girlfriend took her Miata to the dealership with a P0012 code showing, and the dealer told her that the code means that certain parts of the engine aren't getting oil. They flushed the oiling system(whatever that means), changed her oil and filter, and sent her on her way. The check engine light was back on again the next day. This makes no sense to me. I did however read on the net that the slow timing could be caused by "continuous oil flow to the VCT piston chamber." This is not the same as "parts of the engine aren't getting oil."
Is the dealership trying to rip her off, do they not know what they're doing, or could they have some justification for only changing the oil and filter? Thanks for any advice/

What does the code p0012 mean


Hi Craig, hope your doing well today. The code you have P0012 means: Camshaft Timing Over-Retarded. It could be the Camshaft Position Actuator on Bank 1 or Computer and even Wiring Related. Without checking it out there is no way of knowing which is the problem. Unless you have a lot of money and just want to try the actuator, I suggest you have it checked out. Hope this helps and have an awesome day Craig!

How to fix the faulty code p0012 for 2003 mazda demino


code p0012 refers to the camshaft position (CMP) intake left front bank 1-timting over retarded/ system performance---causes---valve timing, engine mechanical fault CMP actuator wiring. To have the valve timing out it has to be the cmp actuator as the valve timing will not alter unless there is a failure in the variable actuator on the end of the cam shaft. I suggest you consult a mazda specialist mechanic to explain the workings of the cam shaft

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.

The service engine soon light came on in my 2003 Ford Explorer. What does that mean?


The service light can come on for many reasons. You need to ask a sales clerk at the local auto parts store to read the codes for your car and tell you what the codes indicate. When you get them to tell you, pay attention to the the last code (most recent) and instead of trying to replace parts based on the code readouts, instead you should post on fixya what the codes indicate and experts can then give you suggestions to help you fix the problem for the least expense.

2001 Miata check engine light on. [cause is P0012]


The cam angle sensor need to be replace. Once it's cooked it will never the same.

Have to consider moving to synthetic oil (Like Amsoil) or remove the front license plate (please check state regulation first).

=====

I'm using Amsoil Synthetic
10W-30 in summer and 5W-30 in winter

Use 65/35 Amsoil coolant mix ration instead of 50/50

Removing the license plate does help air flow.

Clean junk collect in front of the A/C condenser and radiator.

Check radiator cap's plastic gasket.
Get a Rad-Cap

Check/Clean the ECU contacts with CRC electronic part cleaner,

@ 85,000+ miles be prepare for timing belt + water pump change.

Clean / change temp sensor ///// monitor electric fan for operation.


Cam sensor can not be overheated.

<230 F is ideal

I listed everything that can keep the motor cool.



Please rate my answer if it's helpful to you.


Cheers,
