Hi all, just had a breakdown on the dual carriageway, first the antipollution message flashed and then a loss of power. Had the rac come out and I read the codes (see attached image) he was unsure about the thermostat faults but said the misfire could be the coil pack needing to be replaced. The temp gauge did not go up but the fan did stay on for 5 mins after engine switch off. Also I don't know if this could be related but my air con stopped working 2 days ago.

Any help much appreciated. Thanks

Just to add when the rac guy came and revved the engine there was no misfire so I drove home and the car was running fine . Also the fan didn't stay on this time but the antipollution and engine management light remain on.

Really puzzled and don't know what my next step should be.

Sorry forgot to add the car is a 1.4 vti 2008. After some digging I have found it could be related to the engine coolant sensor being corroded or the thermostat housing needing to be replaced? I will check sensor later and have ordered a thermostat for Tuesday in case.

Does this sound like the right thing to try first? Also im still confused aabout the cylinder misfire fault codes. Could the two issues be related?

coolant sensor seems a weak point on this engine, but check for water in fusebox and ecu also.

you may need to reset any codes after.

Hi stripe, just had a look and can't see any coolant around ecu etc. We took the temp sensor off and couldn't see any corrosion but we then tested by putting it in boiling water and the reading didn't change so think it is the sensor.

Any idea if this could have caused the misfire codes? They have self cleared now but there was a definate loss of power but didn't seem like a misffire. I take it I'm ok to drive until I get the new sensor on Tuesday? Cheers

just peugeot electrics? had all sorts of codes in the past, just make sure you pop a battery lead and unplug the main connectors to check for water.

hopefully its just a duff sensor confusing the ecu and throwing out the timing.

Fitted new temp sensor today and cleared the codes and so far so good. Air con back working aswell.

Strange thing happened yesterday after checking the sensor etc. My remote key fob decided to work after a year of it not working, had it to peugeot in this time who didn't know how to fix it. However after an hour it stopped working again :-(
