Hi

Has anyone experienced the PO62D and E driver open circuit bank 1 and 2 codes before.

Replaced inlet manifold and the car wont start, now showing above codes.

Rigged up a test bulb and connected to each injector plug, no pulse light to it.

Baffled, anyone experienced the codes before.

Thanks

Gerry

Wiring looms have been know to break, did you disturb the wiring when you did the manifold?
Using a test lamp might not be a good idea as you may overload the circuit, also a tungsten lamp may not respond quickly enough to show the pulse, an LED with a resistor would be better, ideally an oscilloscope should be used.

Only part of the wiring that was disconnected was the injector connectors.

Test bulb was the only thing I had to hand to test if the injectors were pulsing. A wee improvise is needed sometimes
 
Hi

may i ask is this for a TDV6 or TDV8 plse and what year / auto, manual , many thks

hiya , many thks and no probs , lol

personally I’m not up to speed with the TDV8 , my knowledge is with the TDV6

I’m wondering and the other members may be able to confirm this if it’s possible , by disconnecting the battery and doing a continuity test on each end of the loom to ensure when the loom was disconnected that a break hasn't occurred , or maybe a fuse has blown ???

know thats not really much help to u, but will have a dig through some of my links to see if I can find anything out for
You

there are some extremely knowledgeable people here and will be able to help a lot more than I can

hopefully it’s something simple and u haven’t damaged the ecu

Hi

Firstly many thanks for your kindness, very much appreciated.

There isnt much difference with the V6 and V8.

I could always try, no hatm in it, theres something stopping the injectors from firing, either fuel or ignition.

There is fuel at the rail, so must be wiring or ECU atea, perhaps if powered by a fuse

should have been a straight forward job lol

Cheers

no probs and ur very welcome , indeed it’s always the way with the infamous 5 x min jobs, lol

sounds daft I know , but have u had another look to see that everything has been reconnected ,, alas u walk away to clear ur head to then come back with a better mindset of going through everything again

just found this ref to that code

Causes for this code may include:
Open or shorted wiring or connector in the injector driver circuit for bank 1
Defective fuel injector
Bad PCM or EFI controller Controller programming error

will keep digging ,by the way is the engine the 4,4 jag engine plse

The wires can break at the connector when disturbed.
As I said, the lamp may not prove anything, depends on the length of the pulse and the voltage

Beat me to it!! :rolleyes:
I'd go back over everything touched and double check.. One question, was the engine turned over with the injectors unplugged? It can trigger a none start on some engines. ;)
 
Checked them they are connected, was worth a shot, get the test lamp but its same voltage as a noid light, just differrnt, needed to nartow it down as its needle in hay stack stuff.

Cheers

Hi Mark

yes spent 2 werks going over everything that was done. Guy was experienced mechsnic from Arnold C, dont think its anything he has done, one of those unlucky ones as it was running sweet even with inlet manifold issue.

Yes its how to chevk the wiring.

Was thinking ECU but would think it would show show up more.
It is the 3.6 LR/ Ford engine.

Thnks

Gerry
