Any chance you know what the codes 91 and 26 are for G25P-3, thanks

updated software replaced trim valve fixed

Check connections at accell pedal,also have seen code come up due to poor connection at SECM (check for ty wrap around connector that should not be there).If connections OK, the SECM may need to be flashed (updated with laptop).

codes 74 73 69 rebuilt mixer now just have 69 replaced pedal assy still have code 69

key on, pump pedal 3 times, count engine light flashes (first flashes of 1 and 2 do not count) fault codes are two digit numbers (71 ,72 ,74 etc) probably need to clean mixer and vaporizer ,to clear codes(pump pedal ten times within 5sec.)if codes do not reset your problem is solved
