#138326, "RE: Car goes into open loop near 0 vacuum" In response to In response to 11
I changed to a new TPS, just in case. Did not solve the issue.
Still logging the MAP sensor voltage output, and it is absolutely not the cause.
I don't know what else could possibly be pushing the car into open loop. The only old sensors on the car now are the crank and cam sensors. But if they were the cause, I'd expect sputtering and misfires.
I'm wondering if the O2 harness is shorting out. I can't explain why it would only occur intermittently as I'm accelerating or when cruising on the freeway. But I don't know what else could throw the car into open loop at this point.
