I have the dreadedPO270 CODE I picked up the sensor today and I don't know where it is The Hayes manual does not show it for the 1999 modle year. The truck has the 318 motor I don't know what tranny it has yet.Pleae help if you can Thanks

 

Maybe your code is P0720 not P0270? P0720 is for the output speed sensor on the transmission.
