Cold Air Intake and Check Engine Light
I just installed a Cold Air intake and I am getting a check engine light on.
I am assuming because of the MAF
Is there a bypass for this?
thanks

1:Turn off the ignition of your vehicle and open its hood.
2: Disconnect the negative battery cable (red). Locate the mass air flow (MAF) sensor on the air intake.
3: Grasp the wire harness that connects the MAF sensor to the power unit in the engine compartment and gently pull it out of the MAF sensor. This will disconnect it.
4: Reconnect the negative battery cable to the battery and close the vehicle's hood. When you start up your vehicle now, the vehicle's computer will not look to the MAF sensor to check air to fuel ratio, but will bypass it and go to the O2 sensor to calculate the amount of fuel to mix with the air.

Before you do the reset as above, bring it to a local Auto BM store and ask them to tell you what the CEL is. Then post it here so we can check it out.
