P0219

P0219-ENGINE OVERSPEED

For a complete wiring diagram Refer to Diagrams/Electrical. Electrical Diagrams


Theory of Operation


The Transmission Control Module (TCM) receives a engine rpm over the CAN bus. If the engine rpm exceeds a predetermined value a DTC will set.


- When Monitored:

Ignition on, engine running with the transmission in a valid forward gear.


No active CAN Bus DTCs present.


System voltage between 9.0 and 16 volts.

- Set Condition:

Monitored engine speed over the CAN Bus is greater than 6800 rpm for the period of 100 msecs.







Always perform the CVT Pre-Diagnostic Troubleshooting procedure before proceeding. CVT - Pre-Diagnostic Troubleshooting Procedure



Diagnostic Test


1. CHECK FOR OTHER TRANSMISSION DTCS

With the scan tool, check for other transmission DTCs.

Are there any TCC, gear ratio and/or speed sensor DTCs present in addition to P0219?

Yes

- Refer back to the CVT Transaxle Diagnosis and Testing and perform the appropriate symptom. If speed sensor DTCs are present, perform their respective tests first.

No

- Go To 2



2. CHECK FOR ENGINE DTCS

With the scan tool, check for engine DTCs.

Are there any engine DTCs present?

Yes

- Refer back to the Engine Diagnosis and Testing and perform the appropriate symptom.
- Perform CVT VERIFICATION TEST. Verification Tests

No

- Go To 3



3. CHECK IF DTC RESETS

With the scan tool erase transmission DTCs.

Test drive the vehicle and try to duplicate the setting conditions.

Pick the answer that best describes your findings:

DTC resets with a speed sensor DTC

- Refer to the Transmission and Drivetrain and perform the appropriate symptom.

DTC resets without a speed sensor DTC

- Replace or repair the CV Transmission as necessary.
- Perform CVT VERIFICATION TEST. Verification Tests

No

- Go To 4



4. INTERMITTENT WIRING AND CONNECTORS

The conditions necessary to set this DTC are not present at this time.

Using the schematics as a guide, inspect the wiring and connectors specific to this circuit.

Wiggle the wires while checking for shorted and open circuits.

Were there any problems found?

Yes

- Repair as necessary.
- Perform CVT VERIFICATION TEST. Verification Tests

No

- Test Complete.
