After instaling my Cold Air Intake and bypasing the Coolant Intake on the throttle body, I am recieveing a Check Emision System error light. It also promps me to enter a code on the nav screen. Any ideas what I need to do?


I'm still using the stock MAF and I unhooked the neg terminal to reset the computer.

Put the old intake back and see if it resets perhaps?

I'm still troubleshooting this problem, I need to make sure the mass air flow sensor is pointing in the right direction, can someone tell me if the plug on their mdx is pointing to the front or rear?

I've made some headway tonight. The CEL was caused by the MAF not being installed correctely, and the code on the nav system was a result of the ECU being reset. This is a security code to protect against theft. The code can be found in your owners manual pack.
After entering the code, everything was working.
