Ford V-10 Check Engine Light

[Tommurphy101]

I just took my 2002 F53 MH to the dealer for the Check Engine light. They tested and found several faults. One engine miss code for Cyl. 6 and several for the trans. The Codes are P0783-P0720-P0722-P0303 and P0316. They wanted close to $300 to tell me what the code mean. My coach also has a Gear Vendors Under/Overdrive. Any suggestions as to where I can get the "Magic Decoder Ring"?

P0783 = 3-4 gear shift error code
P0720 = Output speed sensor circuit malfunction
P0722 = Output speed sensor-no signal

P0303 = Cylinder 3 misfire
P0306 = Cylinder 6 misfire

I don't show a code P0316

Here's a handy code listing for the 700 numbers...you can select all the groups from that webpage

P0700 to P0799 listing


All the transmission codes could be caused by a defective output speed ssnsor. You might want to do some googling to find out how to test the sensor.
