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. Testing and Inspection


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

- 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 test.

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.
