Default Expert Temperature / Fan Fault ** Please Help **

Hi All,

Have a really annoying problem that is hard to rectify.

The temperature gauge the other week flew into the red, stop flashing on dashboard and engine went into limp mode.

Engine had only been running for a minute.

Checked coolants etc which where still cold, however, fan continued running even though engine had been turned off.

Garage changed temperature sensor and re-done wiring to the clip / harness as one of the wires was not connecting properly.

Problem still present, when connected to garages computer temperature readings show normal.

I can physically (without starting the engine) turn the ignition on and off several times and get different outcomes, for example, this morning, vehicle had not been used for 2 days, it went straight into the red, stop light flashed and fan had kicked in.

Turned ignition off then back on (without starting engine) and now the glow plug light comes on (even though definately not cold enough to require this), stop light still flashing, fans kicked in again and red light on temperature gauge on however temperature gauge at zero '0'.

Any ideas of where I should get mechanics to look?

Nearest Peugeot dealer 40 miles from me so that makes it tricky getting it there to them.
To add further, not sure if relevant or not but noticed few weeks ago also that the battery light was dimply lit on the dashboard, only dim not full.

Alternator and battery changed 6 months ago and tested by garage whom confirmed battery charging correctly and alternator doing its job.

Occasionally, when start it, I get nothing, bit like battery been totally disconnected. Turn the ignition off and back on and starts fine. This happens bout once in 100 starts.

Not sure if relevant but this was a problem that seemed to appear few days before temperature problem described above so wanted to add this information incase it has a relevance.

Thank you

Not an expert with Peugeot but I think you could start with checking and cleaning the earth strap on your gearbox. I have a similar problem and have found this suggested elsewhere.

It's not difficult to check yourself if you have some simple tools. Check the soundness and cleanness of your battery negative terminal. Follow the black cable down from there to the gearbox. This junction is next. Undo it, clean thoroughly and reconnect. It will probably look fine but that is no guarantee it is electrically sound under heavy load. Then follow the cable from the gearbox to the left wing. Disconnect there, clean and reconnect.

A dirty main earth connection can definitely cause the lack of anything on start you are getting. As I said this has been suggested by others as a cause of the dreaded 'STOP'/temperature issue too.

I would also look into the soundness of the connections on the fan drive relays in a box on the front surface of the fan. And there is also a suggestion that the temp sensors sometimes crack and give this problem too.

Good luck.

Check the date, the problem was in June 2011. The owner has probably fixed or scrapped the van by now.

Hahaha, thanks Gibbo, just found it in passing after posting with similar problems and replied too hastily. Danger of relying on computer search function and not grey cells, (still got both of them but elastic band has snapped). Dooohhh!

Still, that's another 'senior moment' safely weathered. Surviving every one is a little victory!

Sorry guys, eventually found the fault and thought had replied back.

It so happens the temperature gauge wire at the ECU plug had came loose hence the problem. Re-located back to ECU and job done.
