Below are the causes of the automobile fault code p27ad, which include Solenoid Valve Characterization Reprogramming.

  • The automobile fault code P27AD can be caused by a Solenoid Valve Characterization Reprogramming issue.
  • This can occur due to a malfunction in the solenoid valve, which can cause the valve to stick or fail to open or close properly.
  • Additionally, the issue can be caused by a faulty wiring connection or a damaged solenoid valve.
  • Other potential causes of the P27AD fault code include a malfunctioning transmission control module, a damaged transmission fluid pump, or a clogged transmission fluid filter.
  • It is important to diagnose and address the root cause of the fault code to prevent further damage to the vehicle.

To fix the p27ad automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code P27AD, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors for any damage.
  • Look for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P27AD has an estimated repair time of 1.0 hour.

The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of P27AD will range between $75 and $150, depending on the repair time required.

The P27AD fault code is related to the Transmission Control Solenoid Valve 7 Calibration I. The solenoid valves have a unique current versus oil pressure characteristic that is used to properly upshift or downshift the transmission. The TCM needs to have the calibration data for each solenoid valve programmed in order to function properly.

If this data is missing, the P27AD code will be set.
