P0219

P0219-ENGINE OVERSPEED

For a complete wiring diagram Consult Diagrams/Electrical.

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.

- 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.

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 category 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 category and perform the appropriate symptom.
- Perform CVT VERIFICATION TEST. Transmission Verification Test

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

- Diagnose and repair DTC's.

DTC resets without a speed sensor DTC

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

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. Transmission Verification Test

No

- Test Complete.
