86 F150 check engine lite

Have you guys run into a situation were the check engine lite stays on and the KOEO, continuous, and running codes all show 11(system pass)?

Its a 4.9. I had a problem with TPS(23). repaired and cleared codes yesterday. Drove around and to work, re-read codes and still all 11's. The lite will not flash during the self test, had to use voltmeter. Also, it used to go out(6 months ago), but when I released the parking brake the impact would cause the lite to come on for a few seconds. Wiring all looks good. Posibly defect in PCM?

Possibly. I believe 11 is "all is well". Have the PCM checked through a parts store's electronics provider for any defects.
