I have a blinking TPMS, I have these codes. I assume this is usually a bad TPMS sensor? Which is on rear left.

Since your getting the 604E, I would check the wiring and connectors at the RDC unit. Could be loose, corroded, or bent pins. If they are good, then replace the sensor.

Here is a link that shows how to test the sensor itself using a multi meter. You may want to consider doing this to see if the sensor itself is the issue.

Hope this helps. Let me know how you make out.
