Diagnostic Aids

If DTC P0123 cannot be duplicated, the information included in the Freeze Frame data can be useful. Use a scan tool information data to determine the status of the DTC. If the DTC occurs intermittently, using the diagnostic table may help isolate the condition.

With the ignition ON and the throttle at closed position, the voltage should read between 0.2-0.9 volts and increase steadily to over 4.3 volts at WOT.

DTCs P0123 and P0113 stored at the same time could be the result of an open sensor ground circuit.
