What is P0732 : Engine Error code Causes Explained
Transmission problems, low fluid levels, and sensor failures can generate the P0732 engine error code, which indicates an erroneous second gear ratio. This guide covers its causes, symptoms, and transmission repair options.
How to Identify a DTCs Number
The P0732 Diagnostic Trouble Code (DTC) indicates an issue with the Gear 2 Incorrect Ratio in the transmission. It occurs when the Transmission Control Module (TCM) detects that the actual gear ratio does not match the expected ratio for the second gear.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
Connect a diagnostic reader to the OBD-II port on your car to get the code and look for any problems in the transmission system that might be linked.
Causes of P0732 Code:
- Low transmission fluid:
The transmission fluid level may be low or dirty. - Faulty shift solenoids:
The shift solenoids may be faulty or have a faulty circuit or electrical connection. - Bad speed sensor:
The input or output speed sensor may be faulty. - Transmission failure:
The transmission may have internal failure, a bad pump, or a bad planetary gear. - Wiring harness or computer issue:
The wiring harness may be open or shorted, or the computer (TCM/PCM) may be faulty.
Risk Level of P0732 Error Code:
The “High Risk Level” warning often appears because the gear ratio issue could be a sign of more severe transmission damage.
When facing a P0732 code along with by a “High Risk Level” warning, it’s essential to take immediate action.
Common Car Brands Affected by P0732 Code:
The P0732 engine error code is commonly found in the following list.
- Chevy Equinox
- BMW x5
- Hyundai Accent
