I have an '01 Dodge diesel 3/4 ton that I rebuilt the engine on and it started right up after bleeding the fuel lines it started right up and ran fine. One of the batteries was dead and I replaced it tonight and went to start it up it just turned over like it wasn't getting any fuel. The overhead display read "CCD" and the engine light was on. The scanner pulled P0122 and P1698 codes. P0122 looks like throttle positon sensor and I can't find the P1698. Could replacing a battery killed the TPS sensor or was it just coincidental? I'd appreciate any assistance or insight anyone has on this.
