my check engine light came on and the codes read P1312, P1334 and at one time the P0340 code. I have been having the intermittent P0455. How can i clear the P13 codes and the 0455 code.

 

What all have you tried so far, to remedy the codes?

For the P1312 and P1334, its usually a faulty Ignition Cassette. Its recommended to only use OEM for those.

 

thank you for the information. that p0455 i get a lot, someone had mentioned to me to temporarily connect a 47 ohm resistor in with the circuit to see if the code still registers. Are you familiar with this experiment?
