My 2006 2.2 Diesel Civic (77K miles) has also started doing this, the Glow plug light is flashing constantly and info display is showing "check system".

I got the two following error codes in diagnostic mode but these seem to be related to the air con system.

PA 51 DTC B1238
PA 51 DTC B2991


I have checked all 4 glow plugs, Resistance is approx 1.5 Ohms, I have also checked the Voltage at the glow plugs which is showing approx 12V when engine is cold and then seems to go to (0 Volts) after engine has warmed up i assume this is normal ?

The car always starts normally even when freezing below -4 Deg C, however I've noticed a very slight jerking when a light throttle is used when going down hill etc.
it's like there is not sufficent fuel getting to the engine, even does it when it has fully warmed up.

I am going to change the fuel filter when the weather is a bit better, I was wondering if anyone knows what the wires do that go into the fuel filter?

Any advice or suggestions would be much appreicated.

Regards
Sunny

Did this get resolved ??:confused::confused:

I have B2991, B1240, B1240 (which seems to have gone again).

Last night I had a duff headlight so had a fiddle. Removed the battery for better access, and the coolant container too. Put it all back together, and the CHECK SYSTEM + ENGINE MANAGEMENT light came on. Disconnected the battery and all cleared.

This morning heading to work, the drive to the dual carriageway was a little sluggish, but I put it down to being the ECU learning again after the reset. Once on the carriageway, the engine was warmed up and I headed for the 60 limit. The turbo never spooled up, and the light and warning returned. A limp home ensued.
Another battery disconnection and nothing changed, I then tried the self diagnostic and the codes above showed.
Reconnection and I went for a quick spin and the turbo is back, it took a moment to learn itself but it's definitely 100% as far as driving is concerned.
A chat to the muppet behind the desk at the dealers offered no help other than a diagnostic check that will tell me what I know already. They wouldn't offer me any help unless I paid for it.


So before I am forced to cough up, has anyone ideas ?? Pretty please !!
I've checked oil, coolant level, and any other fluids I can find.

B2991 - Climate Control Unit Lost Communication with Audio HVAC Subdisplay Unit (with audio system) or HVAC Subdisplay Unit (without audio system)
**Only it seems to show all correct displays and responses.

B1240 - A Problem in the Mode Control Linkage, Doors, or Motor
**not a clue

B1241 - A Problem in the Blower Motor Circuit
**What problem ? Here it says they fixed it, but I can't see how ?

I did tighten the battery terminal which was loose.
I'll check fuses and a do another reset in the morning to see if I killed any.

Thanks for any help guys, I'm hoping it's a fuse or duff sensor that I may (or may not) have spilt coolant on and shorted.

Over to you....

Fuel filter by sounds of it, and wires will be for the water sensor
Thank you for that. I did replace the fuel filter (Hell of a job, 3 hours and blood, sweat and tears!) but it was due a change so it had to be done !;)

However it did not cure my problem!

I am thinking of purchasing a fault code reader, can anyone suggest one please?

Also how can I check the EGR Valve?

Do the glow plugs look the same, mine were worn away one side as a half moon shape, looked as though they had been filed away. If it is the relay, it's £200 to change. I changed mine but it turns out it was a plug after all. So my relay would be for sale if you want it. Let me know and I'll do a for sale ad in the appropriate section.
