Previa Power Problem

[japman]

Guys I need some help here! Previa 2.0 D4d GLS 8 seater. Covered 80K now, fully maintained by the dealers.

Loss of power problem where when accelerating just feels like all the power is not there! On motorway struggles up hills>

I have has exhaust checked including catalyst, air mass meter replaced, egr valve removed and cleaned, turbo removed and new wastegate fitted as turbo was in good shape, injection cleaners, air filter as well as fuel filter and now i am banging my head on a brick wall to gain some headway.

With a Snap on Modus there are no codes on mainframe and no engine light has ever come on? However on the EOBD system we found P0108 mANIFOLD ABSOLUTE pRESSURE HIGH INPUT-P0104 MASS OR VOLUME AIR CIRCUIT INTERMITTENT-P0102MASS OR VOLUME AIR FLOW CIRCUIT RANGE PERFORMANCE- P0110- INTAke air temp sensor circuit 1. Srange thing is unable to clear the codes.

If there is any of you that can help with this strange vehicle please advise. By the way local dealer has no idea whats wrong??

Hello,

I can't help you, but I have the same problem, a lack of power when accelerating, no guts up hills, with no alarms/codes showing. My d4d has 66miles, and no history. The local toyota garage has no clues. Have you had any luck with advice?

Hi!

Just bought a Previa 02 diesel with 132,000 miles. All was fine when i bought it but now suddenly had lack of power going up-hill and didn't want to rev above 2500 revs. It seemed to have lost its umph! when pushed hard.

I cleaned the mass air flow sensor located directly behind the air filter box in the air tube to the turbo and hey presto....It goes like a rocket now!

Hope this helps you guys.
