P27B0Pressure Control Solenoid K Data Incompatible
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- P27B0 closes the data-incompatible series with letter K, and no public manufacturer document uses it. It would describe a tenth pressure control solenoid whose calibration record in the transmission controller is missing, mismatched or corrupt. For comparison, GM's 2020 table checks the records of valves A to H once per power-up and rates failures Type A; the ten-speed there needs only eight such valves. CARB 13 CCR 1968.2 is the legal basis for monitoring such output components. Practically, a workshop would treat K like its siblings: confirm the valve body ID, load the matching data and clear the code. A broken coil or wiring would produce circuit codes instead, not this data fault.
- What you may notice
- MIL on
- Shift quality problems on gears using valve K
- Likely causes
- LikelyValve K data never programmed into a new or used TCM
- PossibleValve body ID in the TCM differs from the fitted unit
- RareSoftware update overwrote or damaged the data block
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
