In my case ( I have a mazdaspeed 6) the ECU is below the steering column, not a big deal to remove it but if your ECU is like the mazdaspeed 3 located next to the battery it's a really simple task literally easy as 1 2 3 remove the old one, out the new one and program it. The programming just...

Yes I have, it was a bad ECU. found one used from Ebay for 50dlls + 70dlls for the marriage and problem solved. What I did to determine that it was my ECU causing the problem was with the car running tap a cable from the negative of the OCV cable and the ground it to the chassis and hear a...

*SOLVED, it was a faulty ECU, now the car pulls hard, indeed, it was a combination of problems (Bad ECU, oil leak to VVT gear)

I bought another MS6 ECU, i'm gonna report results when swapped and programmed.

Also I ran a cable from ECU pin 4s to the OCV connector negative pin and nothing...

Lucky me I found those pages on a forum, I test one pin that have 12v with a test light ( it turns bright) has enough amperage to move a solenoid. If I measure the same 12v cable from the OCV connector connected to OCV the voltage drops a lot, the test light shine so dim. I got continuity with...

I will do that. I just test for continuity between OCV connector (both pins) and both of them lands on the same pin of ecu connector. I don't understand whats going on here.

Also I test the voltage from the OCV connector and the two cables have 12v, it is not supposed to one be positive and the other one negative?

Hello guys, I need your help, my 2007 MS6 have p0012, the PCM is not sending ground signal to the OCV, if I manually add ground to the valve the VVT moves. Is there any ground related to the OCV? Anyone know if the ECU from mazdaspeed 3 is compatible with mazdaspeed 6?

I have the same problem on my speed 6, ECU no sending ground signal to Ocv, did you find the problem?

*SOLVED* It was the fuel pressure sensor, the one that others say that is compatible with mazdaspeed 3 fuel rail (Bosch 0261545038) for me it wasn't compatible because it was reading low and making a noise at cold start, and actually it is physically different. I went to the yunkyard and grab...

Thats what I wanted to know, if p0012 is related to HPFP pressure. Car's running great out of boost, fuel demands are met. I compared the HPFP pressures out of boost with my friend Mazdaspeed 3 and are the same. Also, I ran the car with spill valve disconnected and ran great. The AFR's at WOT...

Also I did timing chain job I just saw a video from Youtube called ''mazda p0012 CEL DTC cause (for those who tried everthing)'' that basically is a leak from the intake camshaft to the VVT, I removed my valve cover and spark plugs and give it a crank, recorded a video and I have exactly the...

Hello guys, I have a 2007 Mazdaspeed 6 that can't pass hpfp 1487 at WOT, this is what i've done so far to try to fix the problem: *switch the whole HPFP borrowed from a friend (I have corksport fuel pump internals in my hpfp in good shape, no scuffs or anything in the internals) *in tank fuel...

No cats and custom tune. When I started with this problem it was a coil connector, replaced it and the issue was gone, but now is doing the same.
