I have an Accord Tourer 2.2 ictdi, had the car for about 7 months now, a
few weeks ago the heater coil display light came on whilst driving under
acceleration, the car went into "limp mode" after a minute or so of
steady away driving it went off.
A friend who is an RAC patrolman plugged into his diagnostic computer
and the fault was a camshaft position sensor fault, we renewed the
sensor £85.00+ vat, cleared the fault code and tried it, the heater
coil light again came on again and car in limp mode.
Diagnosed it again, this time it showed a P1065 fault code, which I
understand is a Honda fault code.
The car starts and runs fine until you accelerate maybe to 3000 rpm then
the engine faulters and if you persist it will go into limp mode.
I am going to put it in for a major sevice pretty soon when finances
allow, just wondered if anyone has any experience of similar.
The fuel filter does not look like it has been changed recently and when
I spoke to the main dealer they said some problems had been experienced
if fuel filters were not changed regularly....Could it possibly be a
fuel flow fault, was my recent thought.
Any help appreciated.

Change the fuel filter & check the earthing to the ECU if you don't want
to pay Honda for a fault code read out.

Nothing to do with "earthing", that is usually shouted as a guess.
If the ECU wasn't "earthed" - or connected to the negative supply it
wouldn't work.
If the connection was bad or a high resistance it would show immediately
as the
car wouldn't start or run. It isn't really an issue with a Honda.
The fuel filter change will make no difference. Learn how a diesel turbo
engine works!

A blocked/restricted fuel filter on modern diesels can cause the vehicle to
go into limp home mode.
Particuarly on Delphi and Denso systems that use a flow control valve on the
vacuum side of the high pressure pump. The ECU will realise that it's not
seeing enough pressure for a given valve opening, and enter into limp home
mode to protect the high pressure pump.

Stop the guessing and save money. Split the engine in to sections, look
at what each
one does - then try to work out why an error code would point to one
thing, but be caused
by surrounding parts.
