Multiple (4) ECU Error Codes !ALL AT ONCE!
My 2007 MDX has 68K... never had any significant problems...
Just returned from 12 days without driving... within 15-20 Miles of driving, I got blasted with 4 error codes ... ALL AT ONCE...!!! As displayed on the Navi system....
Of course, the display tell me nothing (except to go to the dealer ASAP)..
I'm interested in gaining knowledge before venturing into the abyss with the dealer.....
P0154 Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) Heater System Malfunction
61 Vehicle Stability System Error
77 SH-AWD System Error
P2254 Front Air/Fuel Ratio (A/F) Sensor (Bank 2, Sensor 1) VS Line High Voltage
The only unusual thing was that prior to my vacation, I filled up the tank with gas... noticed that the guy pumped regular (of course, I always use premium..)
Don't know if it's related, just thought I'd mention it.
Driving and handling are all okay..
Too soon to judge MPG effect, if any.
When I turn off/turn on the car, the ERG error always comes back right away.
The other codes sometimes re-appear, and other times, don't ?HUH?
I disconnected the battery for 15', cleaned the terminals, restarted MDX...... and after 15 miles, no errors!... (also filled tank with "super premium" gas.
Thanks, in advance, for any insight!
PS: after disconnecting the battery, I was forced to reset the 'code' for the radio.. no problem... HOWEVER.. the Navi system wants a 'code' too... it doesn't accept my previous Navi PIN? What is this all about?... can I bypass this?.. Reset the Navi Code?... HELP! (please)
