Might be a simple question.

If my New MAF sensor wasn't working right would that throw up the code P0100 for voltage problems or would it not work all together as soon as i start the car up and go into limp mode as at the moment it works for a while then drops into limp mode?

Might try in the morning by putting my old Bosch one back on seeing as it just had a split pipe before which would of been making the car go into limp mode before i brought the new sensor.

It probably would mate as they work on voltage.
As the air flow travelling through will increase current and therefore change voltage.

Maybe try cleaning it with some electrical contact cleaner.

Causes

A code P0100 may mean that one or more of the following has happened:

• The MAF may be disconnected, or a wiring connection may be bad
• The MAF sensor may be faulty

Possible Solutions

The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

• Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
• Unplug and reconnect the MAF wiring harness
• Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
• Replace the MAF sensor

I'll Have a look at that then tomoz might even try cleaning them both see what happens don't think it can make it any worse lol

All you do is just spray it inside don't you?

Surpose another way is to find someone near me that knows there MAF works and ask if theyll swap it into mine to try it but i don't know anyone round my way with the same car lol
