Code p2004 saying intake manifold runner control sturck open. bank 1


code p 2004 has two references
intake manifold air control actuator , bank 1 --actuator stuck open====causes ---wiring---intake manifold air control actuator ---mechanical fault
second reference is
intake manifold air control solenoid , bank 1 --solenoid stuck open===causes ---wiring--intake manifold air control solenoid ---mechanical fault
probably means the same as what you have but in a more easy to understand method

P1250


The location of WHAT???

Diagnostic Test Code (DTC) P1250 is a manufacturer - specific code which has a general description of "Pressure Regulator Control (PRC) Solenoid Circuit Malfunction".

The PCM monitors input voltage at Pin number 44 when the ignition is turned on. DTC P1250 sets when less than .44 volts are present. The possible causes are:
> PRC Valve malfunction (open or shorted internally)
> Open or short circuit between the PRC valve and the PCM (control circuit)
> Open or short circuit in the solenoid ignition voltage supply circuit
> Failed PRC valve (stuck open)
> Malfunctioning PCM

Mil comes on with p2004/ check valve stuck open. Where is the check valve located


P2004 - Intake manifold runner control (IMRC) stuck open (bank 1)
Description - This DTC is set when the IMRC is commanded closed, but the IMRC monitor indicated open. This DTC replaces P1518 and P1537.

Probable causes - IMRC monitor signal circuit shorted to PWR GND or SIG RTN
- Damaged IMRC actuator or solenoid
- Blocked vacuum hoses

Diagnostic aids - Monitor the IMRC and IMRCM PIDs. The IMRCM state should change when the IMRC is commanded open or closed.

This control valve generally is located on the back of the intake.

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, have a nice day.

P1512 of my 00 MPV, what is the solution?


DTC P1512 - VARIABLE TUMBLE CONTROL SYSTEM (VTCS), STUCK CLOSED
The air intake hose that goes from the air filter/mass airflow sensor to the throttle body they are common to crack. This air leak can cause a lean condition if that checks out ok then the issue is usually a faulty mass air flow sensor .This would need to be checked next.

Usually the actuator valve is stuck closed. These are the most common causes of the P1512 and possible causes are:
* ECT sensor malfunction.
* MAF sensor malfunction.
* IAT sensor malfunction.
* EGR boost sensor malfunction
* TP sensor malfunction.
* CKP sensor malfunction
* VTCS solenoid valve malfunction.
* VTCS shutter valve stuck closed.
* VTCS shutter valve actuator stuck closed.
* Short circuit between PCM and VCTS solenoid valve.
* PCM malfunction.

I would start with the mass air flow sensor this can cause all these issues. Then the cat. This would be the next step.

I hope this helped (remember to rate and comment this answer).

I am getting a P0031, P1512, & P0421 code


P0031 - most likely pointing to a failed O2 sensor (bank 1 sensor 1 is located before the catalytic converter)

P0421 - failed catalytic converter or a failed O2 sensor

P1512 - intake manifold shutter valve is stuck - may be caused by the O2 sensor, but may not

I recommend replacing your O2 sensor first and see what happens
