2010 207 1.4 vti fault code p1339 cylinder 3help please

Terry p · Sep 4, 2021

Hi all I have this fault with my car that when I have the car running on data on my snap on solus ultra the car air temp and engine temp both reach 100 degrees the engine goes into anti pollution drops cylinder 3 and code p1339 Comes up , the fan brings temp down and if I switch off engine leave for 30 seconds switch on its OK again. I have recently changed plugs ,coil packs, thermostat housing, thermostat sensor, oil pump solenoid valve as these were other fault codes I had on the reader these are now all gone except p1339 which comes back once temp is reached, could anyone advise my next step as I think I need to get peugeot to set temp settings down to cut fan in earlier or something any help would be appreciated..

swap plug and coil from 3 to another cylinder, hit reset and check for codes (cylinder 3 is taken from gearbox side) 100deg is a bit hot but not by much

I tried that and still had fault come up on number 3 cylinder since then I've done compression test all OK next plan of action is to replace ecu, it will bring up this fault when it gets too 100 degrees which takes a good half hour when not moving..

have you bled all the air out the system unscrewing the bleed cap/s? air can gather around the sensor base and make the engine run rich.
would also check the number 3 injector

Hi strip 88 do you mean bled air out of coolant! can a temp sensor cutoff number 3 as temperature gets to 100 degrees and cuts off but the setpoint for thermostat sensor is 105 and when engine is below 100 the low side fan circuit doesn't cut in as if its not being signalled to run.
