Engine/Transmission (1998.5 - 2002) still have ck engine light after changing VP44

Will it go away after several starts or do I need to have codes erased? The batteries were disconnected while the VP44 changeout took place.

What trouble codes are you getting?



See THIS POST for more info on trouble codes going away by themselves.

I would have someone erase it.
Look for someone in your area
with a smarty or OBD 2 reader.

When I changed my VP44 due to the P0216 and other symptoms, the check engine light and P0216 were still there after start up. I plugged in my OBD tool and erased the code. I've erased the P01740 code by disconnecting the batteries but the P0216 didn't erase that way. You can get a lower level OBD II scanner for around the $70 to $90 range, which I feel is handy tool to have around. Regards, Mike.

P1693 (M) DTC Detected in PCM/ECM or DTC

Detected in ECM

A 9Companion DTC9 was set in both the ECM and PCM.



How did you check for codes, you need to see P-Done twice to read codes in both ecm and Pcm. You probably didn't see all of the codes present yet.

I have a question about p1693. All the books say about it is that the pcm detects a fault in the ecm of the cummins. So how do you get into the ecm and dinstinguish what the problem is?
