07 Mazdaspeed 3 CEL P0327, B1318 and U2064

Went to drive the evil car, and it stalled when starting, as well as when I got to the end of my street. Will not idle. Drives ok tho.

Pulled the P0327 and P1318.

Looks like knock sensor wiring or the sensor itself is shot. Anyone got a pic or diagram handy?

 

Whats your fuel pressure look like? I have similar symptoms but im pretty sure its the pressure relief valve.

 

Interesting possibility. I can look. I made it down the street and it stalled when I stopped. The code points to knock sensor too.

 

Had Terry coming to help pull the manifold. And I went to go back it into my garage so he could work on it. Fired up and was perfectly fine. Cleared the CEL, drove down the street and back and is fine. Will start it a few more times today. Fuel pressure was good too.

Christine was pretty mad that I sat in a 2016 Mazda 6 GT last night and smelled the perfume of another Mazda's rich Corinthian leather. Guess I need to just vacuum it when I can, throw in a new air freshener.

Here are pics that got posted to my wall on FB to help anyone who sees this in a Google search. I'll try to find voltages for it too.

 

Just went and started it. Fired up. But CEL.





Fuck.

Shield for wires to Front O2 sensor, Throttle Body, Crank Position sensor, Knock sensor, and Cam position sensor...

ECU pinout found via Google. Now to get a new ECU, harness, and to fix the reason why it fried.

 

I have no ideas.


Have you tried sticking your penis in the fuel filler? Cant hurt.

 

I may try stuffing a rag in there and lighting it.

 

that might void your warranty

and your insurance

and your marriage

 

1) What warranty?
2) Just a felony if I get caught. Which would be bad as it is posted here.
3) She hates my car so this would just be icing on the cake.

 

Thanks to @Mauro_Penguin and Nick!

Mauricio found the shorted wires. The shield wire and knock sensor wires rubbed part of the trans mount over time. Shorted and melted into each other, causing the clusterfuck. No other issues found, ECU opened and the pin was actually fine. Put together and it's alive!

So grateful for my Nator family.

Nick and I took turns defiling your fuel filler neck, while you were finishing up selling those Japanese school girl underwear on the black market.

That's why it kind of stumbled a bit.

 

Nator jizz is more potent than octane.

 

wow that's a weird issue to have. do you have a wire tuck?

 

Nope. Not at all. And nobody's posted the same cause as me so hoping nobody else runs into it. Googled the cel codes yesterday for more info...found this thread.

 

hmm, well I had a weird issue myself. the rear o2 wiring that runs by the trans some how had wire exposed. drove in the rain one night and car turned off and security light on. also popped fused 69(not joking lol) put a new fuse in and it popped the sec the key went to on. 2 days later I put a new fuse in and no pop and car started. that's when I went digging and found the small bare wire. my point was that.... sometimes the littlest shit makes for the biggest issues.

 

Such insane crap. Nothing "oh, everyone gets this".

I suppose I'll get a P2187 a random misfire now...

 

for your sake I hope not!

 

No shit. 1/2 the threads get posted and no resolution.

 

Harness short prevention system has arrived. Instructions look simple. (I looked at one page).

I'll throw a write up on it too. Looks pretty rad. Already added 10 hp to it as well.
