[Engine] fault code query
#1
New to this forum,so apologies if this has been covered before.
2003 2.0HDi management light comes on and engine won't rev above around 3000.
Faults listed are P1350,P1352,P0113,P0102.
Any thoughts on where to look gratefully accepted.

Did you clear them and see what re-appeared?
Second 2 are faulty airflow sensor and don't usually put it in limp, but you could try running it disconnected to see if that helps. First 2 could be injectors. Does it smoke or misfire?

Not sure if codes were cleared - this was done at local garage.
They suggested dis-connecting air flow sensor - this did not make any difference.
Engine does not smoke or misfire - when management light goes out the van drives as it should.

The first 2 codes are to do with glow plugs so wouldn't give the problems you have, however some code readers can give these faults when there is an injector problem. Ideally you need diagnostics with live data so you can check rail pressure (and all other parameters) Also perform a leak off test on the injectors. You don't need anything fancy, you can cobble some up out of some plastic tubing and some clear bottles.

Thanks for that - I'll cobble up a leak test over the next few days and let you know.
Should an injector be u/s,is this the terrifying job I'm led to believe it is?

You are looking for one or more injectors returning excessive fuel. The injectors can be a pain to remove, but soak them for a couple of days with plus gas and warm up engine before removal.

Leak test done and all looks about equal.
The one thing that I've noticed is that the plastic T-pieces have been held tight by tie wraps - surely a rather non-standard cobble-up?
Can they be replaced reasonably easily?
Also a 2-pin plug connector with red plastic top adjacent to radiator top hose is loose - the black plastic clip has partially broken and been secured with tape (it still feels loose) - could this be part of the problem?
