btw if you want the ESM yourself, see this thread, the link for the download is top of page 2 --> http://typeaccord.co.uk/forum/topic/19286-haynes-us-accord-workshop-manuals/
Looked to me like a lot of things were disconnected for some reason when the ECU was powered up.freddofrog said:Here are the correct translations of those codes in the ESM
P0098 IAT Sensor 2 Circuit High Voltage
P0108 MAP Sensor Circuit High Voltage
P0113 IAT Sensor 1 Circuit High Voltage
P0118 ECT Sensor Cricuit High Voltage
P0193 FRP Sensor Circuit High Voltage
P0403 EGR Valve Circuit Open
P1248 APP Sensor A/B Incorrect Voltage Correlation
P1384 Glow Plug Circuit Malfunction
P2017 IMRC Valve Position Sensor Circuit High Voltage
P2138 APP Sensor A/B Incorrect Voltage Correlation
Depending on how long those codes have been stored, there could be an over-voltage issue ?

The ECU has specific codes for out-of-spec voltage conditions (e.g. P16A4), so I'd ***ume there be an over-voltage DTC? Interesting to speculate (like some sort of forensic investigators in a really boring TV drama) but probably not useful to the current problem!
Those codes point directly to the APP (throttle) sensor, which has no direct interaction with the 'swirl valve' (which is actually the Intake Manifold Runner Control). It's a common enough problem, which you might fix using an electrical switch cleaner, ***uming it isn't actually damaged.chesjak said:Well guys
Thanks for your continued help on this.
Having cleared the old fault codes which my Honda main agent didn't bother to do it has cleared the muddy waters.
I have just been out for a drive and the engine has gone into limp mode twice.
Both times the fault codes that have come up are P1248 and P2138
Having read the contents of your link earlier John-G, I might be wrong but, it does seem to point to the Throttle sensor which in turn will affect the swirl control. Am I correct?
I will have a good look a it again tomorrow and see what I can find. It would be great if that is the problem because I am getting really P**ed of with this.
Cheers Guys
Sorry, wasn't shooting!freddofrog said:don't shoot the messenger
You've got the ESM yourself Jon, why not use that rather than "search the forum"
If I may be uncharacteristically pedantic (LOL) it's not correct to call the IMRC a throttle body. It doesn't throttle, it diverts air flow in order to optimise the intake resonant path (and to generate 'swirl' on a petrol engine).honda_saj said:Thanks jon_g another one that you have resolved glad all sorted when I removed and cleaned my throttle body, maf, map sensors the car drove lovely and in sure mpg went up

But not on diesels they weren't! And neither were throttles.honda_saj said:Correct old school back from the days when carbs were around
Ah. Makes sense now!honda_saj said:Hi Jon,
I own a petrol and have more experience on petrol I am like a novice on diesel engines I can troubleshoot and diagnose but don't really like diesels never was a fan of diesels

Forgive me if you've already said and I've forgotten, but do you have a diesel or a petrol Saj?
