These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

My more mechanically-savvy friend figures the very least we can do is to use some contact cleaner and clean as many contacts as we can.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

7 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Planet-9: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1Original post

I've searched for this issue, but it doesn't appear anyone is having the same symptoms as me. I've been having intermittent issues with a "PSM Failure" error popping up. If I'm at a standstill, the engine dies and I have to restart the car. If I'm moving, it feels like the engine stops, but then refires from simple momentum. What will happen is that as I'm driving along, I will get the beep and the PSM Failure pop up, my revs will drop to 0 and instantly bump back up to where they were. This is also followed by a relatively hard kick from the car too (makes sense if the engine dies then immediately goes back up). All of the results I find when I search have been related to replacing batteries, which I don't believe is my problem. I've taken it to my mechanic who stated that the error code he read is a generic code that suggests something cannot communicate to the ECU (this was a couple months ago, so I don't recall exactly). He stated that all he can do for now, if I so choose, is to simply start replacing parts piecemeal or brute forcing the diagnosis, both of which sound $$$ to me. My more mechanically-savvy friend figures the very least we can do is to use some contact cleaner and clean as many contacts as we can. Any other suggestions? Anyone experience this same issue?

POST 2Original post

Sounds like you are briefly losing battery voltage . That could cause the car to die. Also every time I disconnect the battey, I get the PSM light on the dash. It goes off after a few blocks down the road.

POST 3Original post

I have seen mass airflow sensor do similar things wouldn't be bad idea to check it out. Sent from my iPhone using Tapatalk

POST 4Original post

Agree with Poorsche X, sounds like loss of battery voltage/connection. I too had the PSM failure light go on after disconnecting the battery. I would have the battery checked and clean all the terminals as step one. Good luck

POST 5Original post

There is a ground cable to that goes to the top, middle of the engine right behind the firewall that is notorious for getting corrosion and thus and bad contact.

POST 6Original post

You might also check the negative battery cable where it connects to the body. It can corrode and cause strange electrical behavior.

POST 7Original post

That is the power cable so be careful not to touch the body. Or disconnect the battery first so you don't short out the battery. Sent from my iPhone using Tapatalk
