How to: 3 Check Engine lights : Ignition Coil Knock,1-4;Camshaft Position Sensor
Hey Saab folks! I have a fine 2001 SAAB 9-5 wagon, 2.3t engine, but she can't pass our NYS inspection,in part because of 3 check engine problems:
PO340 Camshaft Position Sensor A, Bank 1 Circuit Malfunctiion
P1312 Ignition Coil Knock detection, Cylinders 1 and 2.
P1334 Ignition coil knock detection, Cylinders 3 and 4.
I am unclear if my friend and mechanic John can fix them; Have any of you all worked on any of these problems, and remember what you did? The Saaby is running well, maybe the MPG could be a little better, but she has power and sounds smooth.
Any ideas?
Thanks,
Tunk
