1996 Ram 1500
with 5.2l / I have installed a new crank sensor, new cam sensor pick up unit in distributor and a new PCM. Took it for a test drive and it set the p1391 again and now I also have the p1398 running out of ideas. the harness appears to be in good shape. it checks out ok with a meter.
JA: Sometimes things that you think will be really complicated end up being easy to fix with a Dodge. The Dodge Mechanic I'm going to connect you with knows all the tricks and shortcuts. Are you hoping to fix this yourself?
Customer: yes, I am a professional mechanic
JA: Great! What have you tried so far?
Customer: checked harness, replaced sensors and PCM
JA: Is there anything else the Dodge Mechanic should be aware of about your Dodge?
Customer: it has 136000 miles on it and I drive it just occasionally
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Dodge Mechanic about your situation and then connect you two.
