Unfortunately, because I have fitted grill mesh, I have to remove the bumper (again) in order to get to the trapped sensor.

Read full discussion summary

Leading evidence: 'Install grill mesh, i have' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'sensor, or perhaps a dodgy connection' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check should confirm' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Got my car back from garage after having new s/s exhaust manifolds fitted (glad I didn't attempt this) and found the sensor has fallen behind the bumper grill (must have been when I removed it to replace the horn

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.

POST 1 / ORIGINAL POSTEROriginal post

My 1998 996 temperature sensor appears faulty. I am getting readings from 19degrees to 38 degrees showing, when obviously this is incorrect (unless we are experiencing very erratic sun spots) Is this just the sensor by the front requiring changing or is there a problem with something else at the other end behind the dash? It's not really an urgent issue but strange that it's only just started to occur. John

POST 2Original post

Most likely the sensor, or perhaps a dodgy connection. Is it properly clipped into the bracket? Sometimes they drop down, and get close to the radiator, giving a false reading. A new sensor isn't expensive. £19.30 inc vat. Part No: 958.505.535.00

Thanks all for pointing out such an obvious solution John

POST 5Original post

cut a small hole in your mesh grill to poke the sensor through. otherwise the pressure of the grill when you reassemble will pop it out again

POST 6Original post

You continue to be my hero John. There is growing complexity in what you'll tackle - I'm still only washing & polishing oh and driving! Paul.

POST 7Original post

John, what stainless manifolds did you go for, I am also going to change mine. Alasdair
