My check engine light came on, had test it and it came back P0420 – Catalyst System Efficiency Below Threshold. Tacoma 2003 2wd 4cyl 178,000 miles runs fine, never have had a major problem.

Somewhat off the infosec path, but I recently found a need to break into a GE Concord 4 home security system recently – yes, the commercial/home alarm system with door, glass break, and motion sensors that calls the company monitoring your system when the alarm is tripped. While my home alarm. Oct 24, 2012. How To: Reset Installer Code Concord 4 GE Concord 4 for HS2.

I called a dealership and was told if I needed a new converter it would cost $1500-2100 depending on the type I needed. A call to a muffler franchise said $449 or much less if it was a sensor problem. Obviously I won’t be going to the dealer. (1) I had a new muffler put on about 13,000 miles ago, could that have caused the problem?

(2) What questions should I ask when I bring it to the repair shop? (3) I was thinking of bringing it to a muffler franchise to have it done. Is one of the national chains better than the others? (4) I have very little mechanical experience.

Is there anything I could visually check though before I bring it in? Thanks for any help/advice!
