obdi dtc 99
 

Invalid pcm program? Here's the story, I rewired my eletric fans and what not last night, reconnected battery cables and went to start to check everything and no go. Glo plugs, cranks, but won't fire off. Checked codes and got.32,33,78, and 99. The 32,33, and 78 I've been trying to fix but the 99 is a new code as of yesterday. Any advice?

DTC 99 - Accelerator Pedal Position 2 (5 Volt Reference Fault)

I bumped my pmd extension harness when I was installing relays. It seperated one of my connectors. So the pmd wasn't sending a signal. Reconnected wires and secured them. Good to go!
