Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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

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.

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

POST 1 / ORIGINAL POSTEROriginal post

Hi, I've been chasing down an intermittent shudder/ hesitation for many months now. I've discovered that my DME isn't getting any signal from the TPS. However I've tested resistance at the switch and it is operating fine. Where would the wiring most likely fail? I've tried jiggling the connector while the car runs, but no change. Really hope fixing this will allow me to drive around town in 2nd. The shudder appears with throttle slightly open so cruising is rough. I've also heard of moisture getting into the switch and causing problems.

POST 2Original post

Not that I can help, however model, engine type might assist others in helping

POST 3Original post

have you got a ground supply to pin no.2 of the TPS?, Wiring generally fails with heat/movement so check the wiring by the TPS plug

POST 4Original post

The plug is known as a junior plug/connector I think. I got a new plug from RS components I think and then wires were covered in 500C heat shield tubing, and ran it back to dme. Then terminated it with correct pins. Was a while ago but can be done cheaply and information is out there. Sorry was a while ago
