MAF Question

[Franco]

Hi, Taken from the Porsche manual table - DME ME 7.2 DTCs

P0134 - FAULT TYPE = Precatalyst oxygen sensor, cyl. 1 - 3

Explanation = Signal implausible / Open circuit / no signal

Beware of dealers they tend to change the easiest and most expensive parts first

Check to see if all the wires connected to the sensors are fine, then replace the sensor one at a time to pin point where the problem was.

Good luck

Hi, If you end up needing sensors this place has all the different models to chose from, but i don't know about the prices.
