I finally got the code read, and it says co265 ebcm malfunction. The problem with that is I can find hardly any info on what values to check for. They are tight-lipped in my area and I had to pull teeth to get a free read. What I have done so far since the read, is cleaned the front wheel sensors. Even the backside of the sensor mount, checked all conectors, and made sure power is at the module.
I did notice that both the module/pump and sensor wiring is too close to the exhaust IMO. I also notice the lights come on when its hot under there. In the mornings they're off until I get some mileage, then if I let it sit and cool down, the lights are off on restart. Go back to driving for a bit, lights back on. Maybe. Yesterday was cool and real windy and the lights stayed off until it sat inside for 20 minutes, then back on until the next restart.
The replacement module is $1124.26 ! And I don't even know if thats the culprit. Should I try to get the code read while the error lights are on?
Is there a way to make the pump work without finding a dirt road to where I can hear it kick in while the error lights are off?
I know this is not a serious problem, but its driving me nuts and I have to figure it out.
The only change I have done is hauling much more weight in the last 3 months, and just before this went wacky I started smelling the nice rotten egg smell from the cat. Thats why I'm leaning toward a heat related problem. I doubt its the speed sensor in the tail end of the trans, and the brakelight switch seems a bit out there too.
