So i loaded a superchips program last night and everything ran fine except a kinda shaky idle but i checked for codes this morning and came up with P1694. I dont know if this code was thrown from the programmer or a previous occasion. So can some one tell me what this code is?

P1694 = TACHOMETER CIRCUIT VOLTAGE HIGH

Not sure why the SC would throw that one... maybe some one will chime in

clear it with the SC, and see if it pops up again. maybe when you flashed the tuner to the pickup it set something off.

i'd try giving SC a call, but i doubt anyone will be around till tuesday, maybe take it to a local parts store( checker, shcucks, O'reily) that lets you use there diagnostic tools for free, see if it picks it up and clear it, and go from there.

is this happening? -- (The oil, temperature, and tachometer are the ONLY gauges that are inoperative. The speedometer and gas gauges work fine. The over head may read "NO BUS" or have dash (- - -) lines. Possible P1694 code in the PCM.) the P1694 I come up with from my chrysler access screen if a communication problem. ask if anything else.
