My car won't rev above 3000 rpm.

Unread post by peu206 »

Helo everyvone
-Peugeot 206 1.4 HDI 2006.
erro codes p1352,p0104 .

The car starts nicely and easily in winter and summer.
New air mass meter, new boost pressure meter, new egr, new intake air temperature sensor.

But the car still shuts off...

the intake air mass is 0/mgs...as if the ECU doesn't see the MAF signal(If I unplug the air flow meter, there is no change (engine sound)..)

Anyone have a solution for this?

Thankyou

P104 is circuit code for the MAF, not surprised it reads 0! 1352 can be associated with a missing earth on the end of the cylinder head, so they could be linked? You should be able to find 5v and earth at the MAF.

Both 5volt and 12v are present in the connector,

But the engine control unit would not disable it because of p1352,

it disables it because it does not see air mass but why?
Where should I look for the actual error?
