where to start with these codes ?
Hi,
I have a 1993 f150 truck, suddenly started to fails in low speed until to reach a point where it stoped to work.
It never turned on the check engine light to indicate me that something was wrong, but because it stayed not working I decided to run the "key on machine off" test and it gave me the followings codes in this order:
23 TP OUT OF SELF TEST RANGE
34 EVP VOLTAGE ABOVE CLOSED LIMIT
PAUSE ABOUT 8 SECONDS..
1 LIGHT
PAUSE ABOUT OTHER 5 SECONDS..
22 MAP/BARO OUT OF SELF TEST RANGE
52 TP CIRCUIT ABOVE MAXIMUM VOLTAGE
Where do I have to start to undarstand what is going on ?
I am not mechannics but unfortunatly have no money now to take my truck to the repair center..
Any advice will be greatly appreciated !
Jose.
