Thanks to technological advancements, many automatic transmissions cannot be manually controlled by shifting the gear lever up/down or pressing the shift paddles behind the steering wheel. This process is controlled by a number of sensors, actuators, and wires. If there is a low-level signal from this circuit of components, a DTC P0952 will be recorded.
How severe is the code?
A diagnostic trouble code P0952 is not very severe, but you will not be able to manually control the transmission using the gear selector or the steering wheel ‘+/-‘.
Symptoms
Symptoms of a P0952 include:
- Manual shift function is disabled
Causes
- Wiring damage
- Corroded or broken connectors
- Shift switch failure
How to diagnose the code?
When trying to diagnose an OBDII fault code P0952, it is important to start by inspecting the entire gear lever for signs of water damage due to spills around the gear lever. The wiring and connectors should be checked for signs of damage and corroded connectors. The manual shift switch itself should also be tested.
What repairs will fix P0952?
- Repair or replace damaged wiring and connectors
- Replace the transmission shift switch
