I have a 2002 Dodge Diesel, High Output with 6 speed manual transmission. Banks installed the Power Pac about nine months ago and it is performing great. Last week I got a check engine light. The OD II code is Po216, injector timing circut malfunction. The light reset itself after about 800 miles. ( I called the dealer from the road and they said to finish my trip as long as the light was not blinking. ) On the return trip the light went on again and I took it in for service. The dealer said the injection pump circut is corrupted because Banks tied into it. They reset the light as said "sorry charilie" Chrysler said we can not work on this. The light stayed off for about 300 miles and went on again today. The shop said they will not look at it and said something Banks put in the circuit is causing a momentary fault which turns on the light, but nothing is actually wrong. Does anybody know what is happening and how to fix it or any other suggestions would be appreciated.
