Vehicles are equipped with systems that work together to give you a smooth and hassle-free ride, and one of them is the transmission control system. Code P0701 is set once your vehicle’s powertrain control module (PCM) detects an issue within this system, which includes sensors, solenoids, and switches.

What Does the P0701 Code Mean?

Diagnostic trouble code (DTC) P0701 stands for “Transmission Control System Range/Performance.”

This code is logged on vehicles with automatic transmissions controlled electronically. The system is composed of a control module, sensors, solenoids, a hydraulic pump, and a hydraulic valve body.

The transmission controller receives voltage signals from the engine and transmission sensors. This data is used to determine your vehicle’s shift strategy and electronic pump pressure parameters. This component, along with others like the valves and solenoids, helps make your vehicle’s transmission work properly.

The PCM registers code P0701 once it detects an issue within this operation. The code is usually logged along with other transmission-related codes.

Note: The definition of code P0701 can be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

What Are the Common Causes of the P0701 Code?

  • Low transmission fluid level/low-quality transmission fluid
  • Transmission sensor malfunction
  • Transmission control system circuit problems
  • Mechanical transmission failure
  • Torque converter malfunction

What Are the Common Symptoms of the P0701 Code?

  • Erratic transmission shift patterns
  • Failure of the transmission to shift
  • Decreased fuel efficiency
  • Transmission slippage
  • Delay in transmission engagement

How to Diagnose the P0701 Code

DTC P0701  is a generic code that can be recorded on various makes and models. However, this does not mean that there’s a one-size-fits-all solution for all of them.  Repair and diagnostic processes for this code will vary depending on the vehicle. If you’re not an experienced automotive DIYer, it would be best to leave the job to professionals.
