B1752 — Park/Neutral Switch Circuit Short To Ground

System: Body  |  Type: Manufacturer-Specific  |  Make: Ford

About B1752

B1752 is a manufacturer-specific body diagnostic trouble code recorded for Ford vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

When B1752 is stored, the module has detected a short-circuit (voltage pulled to ground or to supply) in the monitored circuit.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

B1752 is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The Body Control Module (BCM) on Ford vehicles equipped with passive anti-theft and shift interlock systems monitors the Park/Neutral Position (PNP) switch input to confirm transmission selector position. DTC B1752 is set when the BCM detects a short to ground on a PNP switch input wire, meaning the signal is being pulled to chassis or signal ground when it should be reading a defined value matching the gear position. The PNP switch wires should sit at low signal voltage levels that change between values for each gear position, so a steady low or zero voltage that does not change with selector...
