P0732 Mazda Code - Second Gear Error
Quick Answer
This diagnosis monitors actual gear position by checking the torque converter slip ratio calculated by Transmission Control Module (TCM) as follows: Torque converter slip ratio = A x C/B A: Output shaft revolution signal from revolution sensor B: Engine speed signal from Engine Control Module (ECM) C: Gear ratio determined as gear position which TCM supposes If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Shift Solenoids. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0732 Mazda Description
Torque converter slip ratio = A x C/B
A: Output shaft revolution signal from revolution sensor
B: Engine speed signal from Engine Control Module (ECM)
C: Gear ratio determined as gear position which TCM supposes
If the actual gear position is higher than the position (2nd) supposed by TCM, the slip ratio will be more than normal. In case the ratio exceeds the specified value, TCM judges this diagnosis malfunction.
What are the Possible Causes of the DTC P0732 Mazda?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Shift Solenoids
- Shift Solenoids harness is open or shorted
- Shift Solenoids circuit poot electrical connection
- Transmission mechanical problems
- Transmission hydraulic control circuit

Yes, continuing to drive with this code can cause further damage to the transmission and lead to more expensive repairs.
5. How do I diagnose the P0732 code on a Mazda?
Diagnostics may involve checking the transmission fluid level and condition, testing the shift solenoids, inspecting wiring and connectors, and performing a pressure test on the transmission.
6. Is low transmission fluid a possible cause of the P0732 code?
Yes, low or dirty transmission fluid can lead to improper gear engagement and trigger the P0732 code.
7. How is the P0732 code typically fixed on a Mazda?
Repairs may include refilling or replacing transmission fluid, replacing a faulty shift solenoid, repairing wiring issues, or rebuilding the transmission if necessary.
8. Will resetting the check engine light fix the P0732 code?
