Hi Folks. My 2001 Accord EX (4-cyl) is at 102,000 miles and throwing all of these codes...
P0141 Secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2) Heater Circuit Malfunction
P0420 Catalyst System Efficiency Below Threshold
P0700 Automatic Transmission Control System
P1166 Air/Fuel Ratio (A/F) Sensor (Sensor 1) Heater System Electrical Problem
P1298 Electric Load Detector (ELD) Circuit High Voltage
P1768 ???
I don't even know what the last one is. Any ideas for where a novice should start? I'm out of work until my new job starts in about a month, and PA state inspection just around the corner. Also, I was part of the Sept 2002 auto transmission recall covering 1.2 million Honda and Accura models, did need and got a new trans for free, but the extended warranty on the news trans expired at 100k miles incase that is relevant.
