EFI light
« on: October 07, 2018, 05:06:06 PM »
Been having this issue for a while. I start up and the efi light will blink 10 times and then stay on. Can anyone tell me what the fault code is?

Is there any breaks between the flashes? Far as I know there should be a sequence of flashes with a pause between each to give a 3 or 4 number like 0122 or 0351 ect. All the codes are in the manual. You may find your answer starting on page 15-25,26 &27.

Thank you for pointing that out, there are two codes. First code is P138 which is "O2 sensor circuit high voltage". The second one is a little confusing. I triple checked it and it comes out as P1037. Unless I missed it, there is nothing like that listed in the manual. Drop the 1 and you have 037, "O2 sensor circuit heater 2 circuit low voltage". Does anyone have any ideas or thoughts?

I don't know about your 2017 800 but my 2018 ZForce 1000 has an actual OBD2 Port under the dash. It made scanning mine simple. I've had the O2 code forever and I've been meaning to mess with the O2 Sensor Harness but I'm just lazy and don't give a shit. Lol!
