A P0732 indicates the Powertrain Control Module (PCM) has perceived an anomaly in the vehicle's gearshift ratio.
A P0732 refers to an issue in the vehicle's automatic transmission. According to the code, Gear 2 will have been detected by the PCM as having an abnormal gearshift ratio compared to the manufacturer's default standard. Although the seriousness of this issue may vary, a P0732 can have significant consequences on the way your transmission functions.
There are a number of issues that may be to blame for a P0732. The root causes can usually be traced to a faulty or broken aspect of the transmission system:
Low transmission fluid.
A broken or faulty PCM.
Blocked fluid passages in the internal fluid system.
A P0732 may be identified specifically by the reading of a OBD-II trouble code reader. Most often, a P0732 will affect aspects of the vehicle's transmission. Issues with transmission slippage, difficulty shifting gears and lesser fuel efficiency may arise in the event of a P0732. It should be noted, however, that some P0732s may be reported without any of these apparent symptoms.
A mechanic will first input an OBD-II code reader into the vehicle's computer in order to read and identify the trouble code. A hydraulic pressure diagram should be fed into the proper opening in the transmission system in order to take pressure readings directly from the source. The transmission fluid should be tested with a dipstick and checked for problems.
Any diagnostic findings should be compared with the car manufacturer's default specifications in order to pinpoint abnormalities. If there are other trouble codes registered on the OBD-II reader, it may offer additional guidance in finding the root problem.
The source issue in a P0732 code often lies with the inner transmission system. The gear's related shift solenoids are sometimes misdiagnosed as faulty and replaced needlessly.
The severity of a P0732 code will vary depending on the current symptoms. While some cases will involve significant transmission issues, other cases are too mild to have an effect on driving performance. Regardless, any issue that pertains to use of the transmission system should be approached and dealt with as soon as possible. It is not recommended to use a vehicle with faulty transmission.
Circuitry and system connectors should be inspected, and fixed or replaced as is necessary to complete the circuit. Replace any components in the internal transmission system or PCM that have been diagnosed as faulty or broken. If an issue has been found in the transmission fluid, it should be topped up or replaced as needed. Confer with any other trouble codes in order to more efficiently identify which parts need fixing or replacing.
The parameters of a P0732 trouble code may vary significantly depending on the car model in question. P0732 codes are also known to be usually reported in tandem with other codes.
