After extensive searching and trial and error I found that the cause for the code 1518 on my mazda mpv was caused by the plastic clip that holds the linkage for the intake manifold runner had broke on the fire wall side and the linkage fell out causing the runner to stay open. It is very difficult to see. It is on the front( drivers side) of the engine below the upper intake manifold. Remove the air cleaner box and use a mirror and you can see it. Only about 6 inches long. Replace both clips while you are in there because it is a bear to get to. Check this first before you go through the other items like the egr. Inexpensive repair and my code 1518 and the one for randon miss fire went away never to return. Lots of power again. Good luck. Jim

SOURCE: 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

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).

THAT CODE IS FOR THE BANK 2 OR FRONT CATALITIC CONVERTER ON THE VAN. YOU CAN HAVE THE DEALER REPLACE IT OR A MUFFLER SHOP CAN DO IT. THE CAT IS A PART OF THE FRONT EXHAUST MANIFOLD AND WILL NOT BE CHEEP TO REPLACE.
