Toyota Matrix Owners Forum

Driving to downtown last night and suddenly the engine light on ...never had it on for me ever...I thought that because I swap the TRD intake about 2 weeks ago might be the cause. Didn't have any engine light on when I had my cosmo sri. When home pop the hood...disconnect the negative on battery remove the maf sensor - take a look...freakin dirty...clean the sensor with the electrical connector cleaner...pop it back...connect the negative cable. Turn on the car...voila...no more engine light . Wondering if the dirty maf cause this scare for me ?

If it comes back, I'll drop over and read the code for you Bao. I've got nothing else to do theses days.

Ha ha nice Wayne. You have the code reader/reset ? How is the recovering going ?

Crappy - The recovery I mean - no LIFT eh

I know with my TRD CAI, I throw the MAF running too lean code when it gets to about 60 degrees or below outside. During summertime, I am running perfect. I even cleaned my MAF prior to install of the TRD as well.

No it didn't come on for a while now I actually have a code reader and I clear the code. Crossing my fingers. But I think the Oxygen Sensor is getting old I got code P0133 Oxygen Sensor Slow Response Banke 1 Sensor 1
