Scotty1419 Posted August 11, 2011 Share Posted August 11, 2011 (edited) Hi guys I just have two quick questions if anyone has answers i would greatly appreciate it. first off how can i test my MAF Sensor too see if its working properly? i have an obd2 scan tool with diagnostics if thats whats needed? and my second question is how do you plug/unplug your Check engine light on your gauges. i have reason to believe mine was unplugged or something after the 2.2 swap was done because the egr is disconected and closed off and i read that that will throw a cel all the time.. also i was wondering why exactly did he close off the EGR thing when he did the 2.2 swap?thank you Scott Edited August 11, 2011 by Scotty1419 Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted August 11, 2011 Share Posted August 11, 2011 Checking the CEL bulb is easy. Does it turn on for the bulb test when you start the engine? The reason you have no CEL for the EGR might be because the car didn't come with EGR. Year, model, and transmission type will help narrow that down. Not sure what you're looking for as far as testing the MAF. You must be having some sort of running issue (hesitation, lack of power, stumbling) to suspect the MAF is faulty? MAF sensors are not a common failure, but generally if there is an issue with the MAF, it will set a code which should show up in a scan with your reader.

Fairtax4me Posted August 11, 2011 Share Posted August 11, 2011 Ok sounds like the bulb is either burnt out or has been removed. You'll have to pull the instrument cluster out to change it. It's fairly simple. You remove the screws from the trim 2 on in the top two in the bottom, pull it out, unplug the switches, and set it of the way. Move the steering wheel as far down as it will go to get it out. The cluster is held in by I think 4 screws in the corners, remove those and pull it out, you may have to turn it some to reach your hand around back to unplug the connectors. Your car did some with an EGR on the original 2.5. Why it's blocked off on the 2.2, might be plugged up or the valve may be faulty. I'd unblock it, (get a new gasket from a dealer) and pug it back in and see what happens. Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted August 12, 2011 Share Posted August 12, 2011 or go to a parts store and have the codes read. tell the guy your CEL bulb is burned out. they will give you any codes. ask for the numbers, not just the meanings. and have a pen and paper handy to write it down.
