Hi All,

Had the car hooked up today before a run up to Stockport. These are the readings with the MAF disconnected after a trip to Matlock:

B1S1 sonsor bank 1 /274 mv

B1S1 air/fuel bank 1 sensor 1 lean

B1S2 02 sensor bank 1 sensor active

B1S2 02 sensor bank 1 sensor 2 196@idle

B1S2 air/fuel R B1S2 lean

B1 short term fuel trim 0 bank 1

intake air temp 30c

The 02 sensors remain on lean even when you push the rev's up.

Reconnected MAF and went to Stockport. A true pig. Up a slight hill it was foot to the floor other wise flat spots and hesitation. Drove like a real pig. Could not get more than 80mph and that was a serious struggle.

Emission light came on.

P0130 sensor open circuit not present. I don't know if this is the first or last Lambda but I have replaced the first one. Anyway disconnected MAF and drove to Buxton. Spanner light came straight on but drove alot better.

P0110 intake air temp -40 !!!!! high input present.

p0100 mass or volume air flow circuit low input present

P1700 SVS request via CAN present


Cleared codes but still get 

P0110 MAF

TRANSMISSION

P1781 unkown not present

B3435 (0) L/H servomotor term 2/or term 4 not present.

Any enlightenment would be very much appreciated. Is it the MAF? or the Lambda sensor or both? It spoils an other wise nice car thats in very good condition for 11 years old.

Next time its mirrors in and empty the ashtray.......might get 85!

Whats the MAF reading in Kg/h when idling (hot) and with a few revs?

[cem_devecioglu]

seems like your revs are limited.. which leads me to other thoughts..
 
 

[Craig32]

I will do the Kg/H test tomorrow and let you know.

[Craig32]

Cem what are your other thoughts? The Cat? I don't have much luck with Cats my GSi got through 3 and they weren't cheap ones either.

I'll recommend starting with maf.. a guaranteed way is to find a closer member with 2.2 and try a swap with a good one.... so you will eliminate some problems ..
 
 
ps: not related with cat..
 

[Craig32]

Hi Cem, thanks for that.......anyone live around Chesterfied with a 2.2 that would be willing to swap just to see? I don't want to spend on a new one unless I have to . It certainly drives alot better with it disconnected. I will get the KG/H reading tomorrow.
