Had a brown pant moment this morning while overtaking a bus; my 06-plate 2.2CTDi 'misfired' about 3 times in close succession. Had to abort the overtaking maneouvre and pull over.
I've noticed the occasional 'misfire' before under heavy acceleration but they've just been the odd hiccup. This time the car went into limp mode.

The local garage tells me they found "P1066 - fuel rail pressure sensor reports higher pressure than expected" and also a crankshaft position sensor fault.

(Limp mode now over and engine running normally.)

Anyone seen this before? Any suggestions other than get the sensors replaced?

Thanks in advance!

Why do you think its just faulty sensors?

Dielsels dont misfire like Petrol cars. I had a company car that did it once. It turned out to be a compression issue in one of the cylinders due to a bent crankshaft...

Ive heard damaged/blocked injectors can also cause the problem on dielsels.

Also this might help if your mechanically minded and have a HDS:

DTC Troubleshooting: P1066 (95)
DTC P1066:
Fuel Rail Pressure Higher Than Expected

1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3.Do the FUEL RAIL PRESSURE TEST in the INSPECTION MENU with the HDS.
Is the result OK?

YES - Go to 4.

NO - Replace the fuel supply pump assembly, then go to 5.

4. Do the FUEL PRESSURE CONTROL VALVE TEST in the INSPECTION MENU with the HDS.
Is the result OK?

YES - Intermittent failure, system is OK at this time.n

NO - Replace the fuel supply pump assembly, then go to 5.

5. Turn the ignition switch ON (II).
6.Reset the ECM with the HDS.
7. Start the engine. Hold the engine speed at 2,000 rpm (min-1) with no load (in neutral) until the radiator fan comes on, then let it idle.
8.Check for Temporary DTCs or DTCs with the HDS.
Are any Temporary DTCs or DTCs indicated?

YES - If DTC P1066 is indicated, check for poor connections or loose terminals at the fuel supply pump assembly, the FRP sensor and the ECM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
NO - Troubleshooting is complete


Hope you get it sorted buddy

Hi Ash,
Thanks for your help.

I don't think it's faulty sensors, just feel a little disappointed that the garage only suggested that as the first step. I suspect I ought to replace the garage rather than the sensors ;-)

BTW I had to have an injector seal replaced recently. Maybe no coincidence?
