P0234 Generic Engine Overboost

Recommended Posts

Guest liamgleeson02

Hi All,

 

I currently drive a 05 Corolla 1.4 D4D. I get an engine light fault while driving on either a motorway or normal everyday driving. The fault is P0234 Generic Engine OverBoost. Once this happens I tend to get alot of smoke at the exhaust. Smoke will appear at motorway speed 120 Km/Hr at 2500 RPM or 30 Km/Hr at approx 1200 RPM. I tend to loose power from time to time also, on accerlation the I get the rocking affect.

I clean the Air Flow Meter switch got some improvement. Issue return 24 hrs later. So I purchased a new Air Flow Meter switch but the issue returned 24 Hrs later.

 

What can cause this?

Can anyone one assist please.

 

Regards,

Liam

Not many here will be familiar with turbodiesel. Why this is not covered by warranty?

 

 

Hi,

 

It had a 1 year warranty. Not too many Toyota Mechanics familiar with it either.
