So I went to my local auto-parts store to have my DTC read today after the car shutdown again yesterday and my Intune couldn't read the codes, and they show the car throwing a P0219 Engine Overrev code. I'm fairly certain that by Overrev they mean over readline, which I wasn't, I was on the throttle but nowhere near redline, and its an automatic so you would think it would shift before it got there anyways...And I was wondering if this could possibly be a bad sensor or something? Something that mistook acceleration at around 3K RPM for redline? I have read multiple cases of people getting the same code thrown but in each case these people are doing burnouts at a dragstrip or something similar, I was driving and accelerating, no burnouts. Any help would be appreicated.
This is the information from the service manual regarding P0219.

Theory of Operation
The Transmission Control Module (TCM) monitors the engine speed over the CAN bus. If the engine speed is greater than a calibrated limit (see table), the TCM assumes that either the information from the Powertrain Control Module (PCM) is incorrect or that a major mechanical problem exist. Once the DTC is set, the TCM will position the transmission gear into neutral to protect the engine and transmission from damage. The transmission will remain in neutral and will not be revaluated by the TCM until the ignition is cycled.
Engine Overspeed Limit (If Equipped)
- When Monitored:Continuously with the ignition on, engine running, with the transmission in gear with a valid Engine rpm message received at least once, and the CAN Bus Circuit and Engine CAN Message Missing are not active.
- Set Condition:Engine speed is greater than a calibrated limit (see table).
3.0 L (Diesel)4350 + 800 rpm
3.5 L6400 + 500 rpm
3.7 L6000 + 500 rpm
4.0 L6000 + 500 rpm
5.7 L5600 + 500 rpm
6.1L6200 + 500 rpm

Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding (Refer to 28 - DTC-Based Diagnostics/MODULE, Transmission Control (TCM) - Standard Procedure)
1.CHECK FOR OTHER TRANSMISSION DTCS
1.With the scan tool, check for other transmission DTCs.
Are there any gear ratio and/or speed sensor DTCs present in addition to P0219?
2.CHECK FOR ENGINE DTCS
- Refer to the Transmission DTC based Diagnostics and perform the appropriate diagnostic procedure. If speed sensor DTCs are present, perform their respective test first.
1.With the scan tool, check for engine DTCs.
Are there any engine DTCs present?
3.CHECK IF ENGINE MECHANICAL PROBLEMS ARE PRESENT
- Refer to the Transmission DTC based Diagnostics and perform the appropriate diagnostic procedure.
1.Determine if any Engine mechanical problems are present.
Are there any Engine mechanical problems present?
4.CHECK IF TRANSMISSION MECHANICAL PROBLEMS ARE PRESENT
1.Determine if any Transmission mechanical problems are present. 2.Turn the ignition off to the lock position. 3.Remove the Transmission Oil Pan and inspect for excessive debris or a plugged Transmission Oil Filter in accordance with the Service Information.
Is there any debris, plugged Transmission Oil Filter, or signs of an internal transmission problem?
5.TEST DRIVE VEHICLE
NOTE:The Engine and Transmission must not have mechanical problems and be operating normally before proceeding with this test.
1.Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information. 2.Reassemble any previously disconnected connectors and/or components. 3.With the scan tool, erase Transmission DTCs. 4.Road test the vehicle. 5.With the scan tool, read Transmission DTCs.
