n_hudson Posted September 9, 2021 Share Posted September 9, 2021 Just filled up with diesel drive 20 miles and broke down. Code that comes up is p1262, cylinder 2, high to low short. google says it could be a failed injector, wiring or even fuel filter? Anyone has anything similar?

Ian Lockley Posted September 12, 2021 Share Posted September 12, 2021 If fitting a used injector DO NOT RECODE. I paid £110. eBay Quote Link to comment Share on other sites More sharing options...
Ian Lockley Posted September 13, 2021 Share Posted September 13, 2021 Old injector out all cleaned up waiting for replacement. Side note on the fuel return connections to each injector there is a green plastic butterfly. I used a piece of wire bent into a U shape then slipped it around the butterfly and up then bent the wire so I could get my fingers under the hooks Slight pressure and a bit of a wiggle soon had the butterfly's coming up to be level with the blue section. Then a gentle upward pressure popped the connectors of the leak off pipes . To reinstall you would push down on the Blue bit making sure it's locating properly Over the O ring once its down You push down on the butterfly to lock in place. Don't force as they are easily SNAPPED then it's a new kit £17 from main dealer . My injector is badly carboned up at the tip . Fault 1261 no1 injector hi to low short . RAC man says the 2 solenoids it the injector have burnt out. 😳 Once again I was told if you are fitting a s/h injector . DO NOT RECODE.

n_hudson Posted September 13, 2021 Author Share Posted September 13, 2021 I had it at Ford today, they cleared faults road tested car. Drove fine and no codes. I don’t have the confidence to do it myself. Quote Link to comment Share on other sites More sharing options...
MasterTechTip Posted September 13, 2021 Share Posted September 13, 2021 Why did they clear the codes and leave it? This code means the injector has failed internally and needs replacing Quote Link to comment Share on other sites More sharing options...

Drove fine and no codes ??? clearing the code has not fixed the fault - it will be back, sooner than you probably expect. 3 hours ago, Ian Lockley said: Once again I was told if you are fitting a s/h injector . DO NOT RECODE. Why ? it is after all a calibration figure and it is the car you are inputing the data too not the injector. I can believe that the calibration factor will not be exact for a second hand injector but it must surely be more acurate than leaving the car with the calibration data of the injector that has been replaced?

The codes where only stored, not active. if it had failed and was a permanent fault, wouldn’t it still be chugging and misfiring? Quote Link to comment Share on other sites More sharing options...

It should be yes, it's more than likely the internals of the injector have moved slightly and the fault has stopped. I've never known this code not to return as it does indicate an internal failure 🤔 See how you get on I guess, whilst it's not faulting it's not costing you money 😂 Quote Link to comment Share on other sites More sharing options...

It’s someone else’s little project then. im going to run a few bottles of cleaner thru the tank first. Quote Link to comment Share on other sites More sharing options...
n_hudson Posted September 17, 2021 Author Share Posted September 17, 2021 Done nearly 400 miles now, initially took it slow, but steadily giving it some beans to work her. Change fuel filter, apparently it hadn’t been changed in some time and was absolutely filthy, despite on the service docs saying it had. I’ve put some stp cleaner in 3/4 tank to see if that does anything and I’ll probably do it every second tank. The wiring and connections have been checked and the garage think it was a slight blockage that has now worked through the system. Quote Link to comment Share on other sites More sharing options...
