vw polo 1.4 16v g71 sensor p1156 fault code

Post by Chickenjohn77 »

Hi guys

I wondering if anyone has had this problem before on Polo 2003 1.4 16v

Comes up with CEL and EPC light

Scanned with my Ancel scanner and comes up g71 sensor p1156 MAP fault short open / ground.

Checked wiring replaced MAP which made run worse cleaned throttle body and EGR fixed vacuum leak from crack in brake booster hose .


Car has EPC light on but is not in limp mode runs rough when cold but fine when warm and drinking loads of petrol a time

Scanning removes light but comes back instantly

Ideas anyone

Many thanks
