Hey, I just put an Injen intake on my car and about two days later my check engine/ check VSC light went on, i tried resetting the ECU but even after the reset about 2 days later it came on again i had the codes read and its throwing P2195 - (02 sensor stuck lean), anyone know what i should do i would really hate to take the intake off. -- ty

 

Check your MAF for damage. The MAF and the O2 work together to set the correction factor used to calculate the exact amount of fuel you need. If the MAF isn't working right (damaged on install or not sealed, or leak in intake tube near the throttlebody) then the O2 sensor will do its best to compensate, but it can only adjust +/-20% from the table value. If the needed correction exceeds 20% either way, then you throw codes and it's time to find the problem.

 

Hi, thanks for the input, how can i check the MAF for damage?

 

Also if anyone has good DIY MAF cleaning instructions its worth a try--ty

 

First check for leaks. If you have a leak after the MAF it will screw up everything. It's the most likely cause of your issues. Second, remove the MAF if you found no evidence of leaks, and check it for physical damage.

If you have not used an oiled air filter, it's very unlikely your MAF is dirty enough to need cleaning. I would avoid it. I've seen enough people damage their MAFs with cleaning to know it's pointless unless you clearly have no alternative.

 

ok ill check it out thx again!

 

also make sure you installed it in the correct direction. It will only work with the plug end faceing the motor.
