P1687 Chevrolet -

Question

What is this code showing up mow I just changed out the purge vent solenoid when I had a P0449, now I have a P1687? Can you help with this?

Answer 1

Remove the purge solenoid and install the old one, clear the code , you will also need to see if blew a fuse, One the purge circuit it is part of the MAF (mass air flow) and the TCC (torque convertor clutch circuit. ) . this may be a shorted purge solenoid
