What is P07AB?

DTC P07AB is a diagnostic trouble code that signifies a problem with the transmission range sensor circuit. This code is often seen in vehicles like the 2015-2018 Ford F-150 and 2017 Chevrolet Silverado. The transmission range sensor, also known as the neutral safety switch, is crucial for ensuring that your vehicle can only start in park or neutral. When this sensor malfunctions, it can cause the vehicle to behave unpredictably, such as failing to shift correctly or experiencing harsh shifts. In some cases, you may notice the check engine light illuminating on your dashboard. This code can lead to significant safety concerns, as it can affect how your vehicle accelerates or even prevent it from starting altogether. If you see this code, it’s advisable to address it promptly to avoid further complications, such as transmission damage or issues with vehicle control. Ultimately, understanding DTC P07AB can help you maintain your vehicle's performance and safety while also saving you money on potential repairs.

Symptoms

Common symptoms when P07AB is present:

  • The check engine light stays on constantly, indicating a potential issue that needs addressing.
  • You may experience harsh or erratic shifting, making driving uncomfortable and possibly unsafe.
  • Fuel economy could decrease by 10-15% due to improper shifting or engine performance issues.
  • The vehicle may not start in gear, which can be alarming and dangerous if it occurs unexpectedly.
  • In some cases, the vehicle may go into 'limp mode,' which restricts speed and performance.

Possible Causes

Most common causes of P07AB (ordered by frequency):

  1. The most common cause of the P07AB code is a faulty transmission range sensor, with about 60% likelihood. This sensor may wear out over time or fail due to exposure to heat and vibrations.
  2. Another possible cause is damaged wiring or poor connections in the transmission range sensor circuit. Corrosion or fraying could lead to intermittent signals.
  3. A third cause could be low transmission fluid levels, which can affect the operation of the transmission and lead to erratic behavior. Regular fluid checks can help prevent this.
  4. A less common but serious cause is a failing transmission control module (TCM), which can lead to significant performance issues and may require replacement.
  5. In rare cases, software issues in the vehicle’s onboard computer can trigger the P07AB code, necessitating an update or reprogramming.
