OMP kicking up
Hi lads my heat light flashs sometimes and when i check my commander i see that the voltage for the omp is dropping.. then its fine its only for a split second so my real question is if i premix until i get a new omp will i be fine to drive away for now
Thanks |

Thanks for your comment my car is a fd sorry should have said that on first post but anyway i never checked any wires i just went to the sensor check on my apexi commander and thats where i seen the voltage drop

Someone familiar w/FD's will then have to help you.

If it's anything like the 20B in my car, feedback voltage should be relatively consistent. Minor variances (0.01-0.02v) could be ignored safely. but anything in the neighborhood of 0.1v differences should be given your attention. Are you noticing any driveability issues such as the car going into Limp Mode?
Also, is this a consistent issue or intermittent? Intermittent would suggest the OMP's ground needs some cleanup. I would check continuity between the OMP connector and ground. It should read 0.06-0.09 ohms. Repeat between OMP and ECU, OMP & 5v source (I think it is the ECU) and all of the other OMP wires to their respective targets. FDs tend to be hard on their harnesses due to the excessive underhood heat, so it would be wise to rule out wiring issues first before blaming the OMP. |
