P0113, IAT sensor voltage high/open. Any thought or experience? Thanks.

 

Check your connection (Input Air Temperature), should be in your intake manifold, behind your throttle body.

 

Not sure what model bike you have but the following is from the 2006 Dyna Electrical Diagnostic Manual and may be helpful:

P0113 IAT sensor open/high

Check the following:

* Poor connection: Inspect ECM and harness connector [78] for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal-to-wire connection and damaged harness.

* Perform 4.8 wiggle WIGGLE TEST to locate intermittents: if connections and harness check out OK, use a DVOM to check the intake air temperature sensor voltage reading while moving related connectors and wiring harness. If the failure is induced, the intake air temperature sensor voltage reading will change.

* Shifted sensor: Refer to table 4.24. This table may be used to test the intake air temperature sensor at various temperature levels in order to evaluate the possibility of a shifted (out-of-calibration) sensor which may result in driveability problems.

* An intermittent may be caused by a poor connection, rubbed through wire insulation or a wire broken inside the insulation.

Note: All voltage and resistance values are approxiamate (+/- 20%). Measure IAT sensor resistance between ECM terminal 7 and system ground (ECM terminal 26).

If you need it, let me know and I'll post the troubleshooting chart as well.

.
Hold the button down for a few seconds.......... that clears the code.


if it does not appear again, it was historic

if you see it again it is current........ so then you follow yellowhawk's list (for starters)

go from there
