Default Check engine light

'07 FLHX. Just installed a PC IIIr and set the idle position. When I turn the ignition on the fuel pump primes and the engine light goes on then off. When I start the bike the engine light goes on for about 5 seconds then turns off again. Did I throw a code? If so can I reset it? Thanks.

Thanks. I did the diagnosis and I got 3 codes. I got P 0131 (front 02 sensor low), P 0151 (rear 02 sensor low), and P 1004 (system relay contacts closed efi). I also rec'd a code PN 34455-076b. Is that a part # that needs to be fixed? I checked Zanottis and Chicago HD website and the part #'s did not come back as valid. How can I fix the codes? Dealer time? Thanks.

The PN is the part number of the ECM. You don't have to change it. You need to contact power commander and find out if the 02 eliminators can be used on the PCIIIr.

use the o2 sensor eliminators, to clear the codes just hold the trip reset button while on the code untill it says clear. the PN means nothing. most of the codes were prob set when you installed the pc III, since the light goes off, the codes are historic.
