After fixing Code 63 yesterday I Reset My ECM and received code 11. Systems pass. I was very happy to pass so I drove my 89 5.0 LX Convertible Mustang to work. On the way to work my check engine light came on.

So this after noon I did a KOEO test. I received quite a few new codes. This is the order they came in.

21 ACT out of self test range
67 Neutral Drive Switch circuit open (That is because I have my own switch in the car.)
21 Ect out of self test range
22 Map BP out of Self Test Range. (I do live 8,000 feet above sea level)
35 EVP/PFE circuit above maximum voltage. (I have by passed my smog pump and yes I have pluged all the lines.)
51 ECT Sensor Fault or circuit open
53 TP circuit above maximum voltage
54 ACT or VAT sensor fault; circuit open
96 High Speed Fuel Pump; Relay circuit open
22
35
51
53
54
96

What do you guy think? I think I am going to warm up the car. Reset the ECM and then Drive it again. See what reaccuring codes I am receiving.

Thankx
