Pinpoint Test Z: Intermittent
Normal Operation and Fault Conditions
This pinpoint test is intended to diagnose and isolate intermittent concerns for all EEC subsystems. Parameter identifiers (PIDs) corresponding to a circuit can be used to aid in identifying the intermittent cause. Some circuits do not have an associated PID or the PID may not be available and must be measured using a digital multimeter.
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P0219:00 | Engine Overspeed Condition: No Sub Type Information | Sets when the PCM detects the vehicle is operated in a manner which caused the engine speed to exceed a calibrated limit. The engine RPM is continuously monitored and evaluated by the PCM. This DTC sets when the RPM exceeds the calibrated limit set within the PCM. This DTC may be accompanied by other Diagnostic Trouble Codes (DTCs). For additional information on the engine RPM limiter, refer to Powertrain Control Software. If DTC P1285 or P1299 is present, disregard DTC P0219 at this time. Diagnose DTC P1285 or P1299 first. If there are no other symptoms, return the vehicle to the customer with information about the DTC. |
| PCM P0297:00 | Vehicle Overspeed Condition: No Sub Type Information | Sets when the PCM detects the vehicle is operated in a manner which caused the vehicle speed to exceed a calibration limit. The vehicle speed is continuously monitored and evaluated by the PCM. For additional information on the vehicle speed limiter, refer to Powertrain Control Software. If there are no other symptoms, return the vehicle to the customer with information about the DTC. |
