TYPICAL MALFUNCTION THRESHOLDS
INSPECTION PROCEDURE
HINT
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data
the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was
running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data
recorded at the time of a malfunction.
PROCEDURE
1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P050A)
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine and ECT / Trouble Codes.
(e) Read the DTCs.
Result:
HINT
If any DTCs other than P050A are output, troubleshoot those DTCs first.
B -- GO TO DTC CHART See: Diagnostic Trouble Code Descriptions/Engine Control System - SFI System
