thats what freeze frame data is for. it tells you values recorded at time of the dtc being set and (on good tools) expected values also.

Bit the bullet and towed caravan to N. Devon.....crossed Severn bridge and cruising along the M48 toward M5 southbound and Engine malfuction came on and went into limp mode. Pulled onto hard shoulder. Switched off engine and waited a moment, fired back up and continued rest of journey. OBDII later gave no Errors all clear.
Getting back now is a bit daunting....lots of local mileage here without any issues. Can't even get a diagnostic done as nothing flagged, Had similar with Nissan truck and it was the neutral gate switch intermittent.

This should be in previous errors

^^^^ What he said.
The ECU stores fault code history until cleared.

My Mondeo diesel started doing that on odd occasions, usually when cold. Engine light would come on, power would drop off.
Fuel filters needed changing, and it was good as gold after that.

It happened a couple of times on the motorway, when the problem first started, so I dipped the clutch, switched ignition off, then back on, fired it up, on the move, to save pulling over. And I turned off at the next junction, didn't dare go on it again until I got it fixed.

I agree it should...but hasn't. So maybe a ECM fault ....could even be down to mice...
Will put the Fordscan app back on now and see if missed anything.

The fuel filter was changed couple years back and old filter was was spotless, no sign of dirt/water. Re-priming was a nightmare, No priming pump. The first time it came up I had a p2265 error code (water in fuel), but nothing with latest. I wasn't doing a diagnostic on the hard shoulder and no history DTC. According to the app 1,550km since last one.

How many miles is a couple of years? I change my fuel filters every other oil change so at 20000 miles.

I assumed Stoneacre were changing my fuel filters when they did my full annual services.... but it would appear they didn't think it necessary.....

10,000 ish....... total miles 87,000 after 14yrs, oil change every ~6 months. Bulk oil and bulk filters.

wondering if the dtc code history will show up with professional odb interrogator?

 

[prepman]

hmmm.....? 2:30 in....both engine malfunction events occurred on motorway at cruising speed.
Same system I think on my Kuga.

You would have a dpf fault.

You need the codes read otherwise you are stabbing in the dark. Guessing with modern vehicles or unspecific symptom searching is just wishful thinking

According to my cheapo obd unit there are no errors...but maybe a professional unit will pull up the history that I can't see? It's just that it ties in exactly with the circumstances.

You need something capable of reading E(xtended)OBD to get the full codes - but don't take them as gospel, you also need to be able to read live values, particularly pressure & differential pressure values and temperatures. DTC's can be set if a sensor is giving erroneous but still 'in range' values which indicate the problem is elsewhere. The simplest check is that all pressure values are similarly close to atmospheric and the differential exhaust pressure value is close to zero with the key on, engine off.

I can do the live readings, so I'll have quick look.

Got 1.3g/s MAF with engine off. Is that an acceptable zero error? 100 Kpa atmospheric 101Kpa intake all off.
It's booked in on thursday....they also seem to think the dpf is suspect. If the burner needs replacing with a genuine Ford item looking >£K1. They also say they can clean the unit if possible.

You can buy the vaporiser rather cheap.

I see more and more offer launch dpf cleaning seems to work.

I feel your pain doing that master cylinder. My Prelude (which has a lot of similarities with the accord) came to me with a knackered auto box and after a lot of research we decided the simplest thing to do would just be to stick a manual in 'er. I swear drilling the firewall to install the master cylinder was a worse job than actually putting the new transmission in it. I'm fat so had no choice but to remove the entire dashboard and drop the steering column down, and even then it was a mare, killed my cheap drill (apparently they dont take kindly to the large step drill bits) and it took half a day to bleed the bugger!

Worth it though, lot more fun with the manual. Nice revvy engine, never suited an auto very well. No idea why most of the higher spec ones were auto and it's a shame as they will all explode sooner or later. It was Honda's first attempt at using electric solenoids and valves to control a slushbox instead of a mechanical hydraulic valve body and they had a nasty habit of burning out the clutch packs, that or would pop a seal somewhere on the main shaft and lose pressure which again lead to the clutches dying. Sometimes simpler is better, and if it ain't broke then don't fix it - never had a conventional automatic die on me! I suppose they were complicated cars for the time - made 200hp out of a 2.2 litre NA and have a balance shaft, VTEC and other wizardry, oh and don't forget the 4 wheel steering which has never worked on mine

I hate cars too, I will qualify this rant too, with a new clutch for the car I bought last week. Yes, that said crying / ranting sound is me you can here, bloody cars, well, it was cheap.
