jdbob Posted April 1, 2014 Report Share Posted April 1, 2014 Where did it say "manufacturer control auxiliary inputs/auxiliary outputs"? Just going by the number range of the code it's probably the transmission. Quote Link to comment Share on other sites More sharing options...

kostby Posted April 26, 2014 Report Share Posted April 26, 2014 Just noticed that the actual code shown in the pic above is P1674, not P1764. C-MaxSea 1 Quote Link to comment Share on other sites More sharing options...
plus 3 golfer Posted April 26, 2014 Report Share Posted April 26, 2014 (edited) LOL, well that explains it. Under Electronic Throttle Control in the Ford OBD Operations Summary manual: P1674 – Internal control module software corrupted (MIL, hazard, wrench light for Gen3 / Gen4) You probably had an anomaly with software / messaging and thus perhaps sensor inputs couldn't be reconciled and the PCM started ICE. Since the CEL illuminated, it was deemed a hard fault (not intermittent). Did the CEL go out? Did you clear the stored code? Is everything now okay? I would have gone to the dealer to document the DTC for warranty purposes. The dealer would probably run pinpoint tests for wiring continuity and proper voltages. I doubt the dealer would reload software unless Ford directed such. P1674 is a manufacturer specific code and appears to be a "catch all" when there is not a specific fault found in a component which should throw a specific code for the issue. This is for VW : P1674 - Data Bus Powertrain, Implausible Message from Instrument Cluster Symptoms:Function lossPossible causes:Wiring and / or connections faultyFault code stored in corresponding control moduleControl module incorrectly codedPossible solutions:Check / repair wiring and connectionsCheck / erase fault code in Control ModuleCheck / repair coding in relevant Control Module Edited April 26, 2014 by Plus 3 Golfer C-MaxSea 1 Quote Link to comment Share on other sites More sharing options...
