The car was running fine then s/owed down for a light and it went to hell. Ck Eng light and message about limited performance. Ran the codes and I have a Code P2229 , changed the plugs and coils, also sent the processor out to be evaluated. Was told it was bad and it was rebuilt by Module Experts in FL. Still the same. Any suggestions?

 

A quick Google search says "Barometric Sensor Bad". Replace that, and all should be well. Course, it IS part of the ECU, so maybe a faulty flash? I don't know why the plugs and coils, unless that was for something else.

 

If you are still getting a P2229 then it points to the ECM still having an issue.

 

Not being familiar with the current setup, is there a vacuum line running to the ecu like in the old days? Lack of expected vacuum at any given engine range can play havoc.

 

Vacuum sensor, of course. Not a line. Don't ask me where anything is though, there are a LOT (most other people) who know stuff like this.

 

All revealed in the workshop manual and the electrical guide - the latter shows every sensor used by the PCM (aka ECM). Free downloads

 

There are no vacuum lines to the ECU. The ECU was sent out for repair and found to be good by EUC repair in Florida.

Was looking for something I'm missing before I take it to the dealership.

 

I read the few posts that are out there and they say replace the ECU. I sent mine out to ECU repair I Florida and it was repaired and sent back and still the same issue. Before I take it to the dealership I was looking for any other information I could find.

 

Barometric sensor would be the MAP sensor, wouldn't it? Replacing that would be a quick and cheap test before heading off to the dealership.

 

Sounds like you need a NEW ECM ... or a working used one.

As far as i remember, all they do is re-solder everything. Unless they replaced the failed internal component during the repair (which I doubt), the "repair" would do nothing.

Replacing the ECM requires re-programming, so you will need to take a trip to the dealer anyway.

 

No, thats a separate sensor. The manual (and post from u102768) mentions P2229 is related to an internal ECM failure.

 

If you have sdd jlr you can mate a used ECU to your car . I have done this numerous of times. I have SDD JLR setup I can loan if your in the USA

 

You’re braver than me... I wouldn’t let just anyone look at my ecu. And with that code, I can’t figure out why the plugs and coils were changed... as Cee Jay suggests... did you ‘tune’ your car...

 

No vacuum hoses to the ecu

 

There are no vacuum lines going to the ecu

 

There are no vacuum lines going to the ecu or anywhere near it

 

It is misfiring and I wanted to tune it up anyways.

 

turns out the timing chain slipped and it has bent valves.

 

Crap...sorry to hear!

 

That does suck. But its a chain, not a belt. ‘slips’ just don’t ‘ happen’.
(Yes, I’ve rebuilt engines with a timing belt and overhead cam in my youth. It was the only way my father would give me a car)
But I’m afraid I don’t see the correlation between the code thrown and the valve situation. I have doubts.

Count your lucky stars though, that engine could have had enough loose metal in her that she’d sound like a change purse.
