Laymans terms

This code means that the car's computer has detected a problem with the sensor that tells the car if it's in park. It's like when a toy's battery is running low and it doesn't work right.

Explanation

The P07BA code is triggered when the transmission control module (TCM) detects a high voltage signal from the park position sensor/switch B circuit.

Technical description

The park position sensor/switch B is part of the transmission system that helps the car know when it is in the 'park' position. A 'circuit high' condition means that the voltage level detected by the TCM is higher than expected, which can indicate a problem with the sensor, wiring, or connectors.

Symptoms

• Check Engine Light is on

• Car may not start in park

• Transmission may not shift properly

Common Causes

• Faulty park position sensor/switch

• Damaged or corroded wiring or connectors

• Faulty transmission control module (TCM)

Glossary
