Anti pollution Fault on my de-fapped 406.

[Peter86]

Yes doggy - I have cleared them all and none have come back (so far)

Didn't say if it was high or low fuel pressure - how could I tell? And wouldn't a fuel pressure fault be constant problems, not intermittent like I am seeing?

That's why I thought TPS, are they expensive?

Is it best to see which one returns? then go from there?

Didn't someone do a guide on stripping and cleaning a TPS? metal filings causing sensor issues??
Too tired and too hot to think

General code readers may not tell you, (but maybe there are different codes for high and low pressure)?
PP2000 would give you a description and the possibility of logging the values at the instant the error is generated.
As far as I'm aware low pressure will just give you an error, high pressure may stop the engine.

Low pressure could be a hangover from running out of fuel, or a sign of a failing lift pump, maybe a faulty regulator.

I definitely would.

Thanks guys - no faults returned yet. I have a close eye on it.

The TPS cleaning thread would be useful if it exists?
