P0732 OBD Error Code: Problem & Solutions

<<See All OBD Codes

Improper shifts and reduced fuel economy are the major setbacks for this kind of a problem. In extreme cases engine stalling and vehicle dying while slowing can be crucial on road and in extreme conditions. All these are an indication of a problematic transmission thus storing OBD code P0732 in the PCM (powertrain control module) and the check engine light getting on.

OBD code P0732 is defined as Gear 2 Incorrect Ratio.

P0732 code shows up in vehicles with an automatic transmission when there is a problem shifting into 2nd gear, or while driving in 2nd gear. The computer controlled automatic transmission uses multiple gear ratios to increase vehicle speed while maximizing the power output from the engine. Newer vehicles may have more than four gear ratios to improve fuel economy. The computer determines when to shift up or down between gears based on throttle position vs. vehicle speed. The Engine Control Module (ECM), Powertrain Control Module (PCM) or Transmission Control Module (TCM) uses input from various sensors to verify the correct operation of the transmission and its components. Engine speed is often calculated against the transmission speed sensor to determine gear ratio and torque converter slip. If the calculation does not match the desired value, the Diagnostic Trouble Code is set and the Check Engine Lamp is illuminated.

What causes this problem with the Gear 2 Incorrect ratio?

• Low transmission fluid level
• Dirty transmission fluid
• Faulty Shift Solenoids
• Shift Solenoids harness is open or shorted
• Shift Solenoids circuit, electrical connection faulty
• Transmission mechanical problems
• Transmission hydraulic control circuit

1. Automatic Transmission Solenoid - Faulty shift solenoid can be a main cause for gear 2 slipping and thus needs to be checked for and replaced.
2. Transmission Control Module - Faulty TCM will cause abrupt shifts and engine halts. Thus, check and replace the TCM for proper functioning of the system.
3. Automatic Transmission Sensor - Check for faults in the transmission control sensor and replace if needed. Buy new sensor from us!
4. Auto Transmission Torque Converter - In rare cases the transmission torque converter can also be damaged, immensely harming the transmission system. Buy new parts from us!
5. Automatic Transmission Connector - Faulty connectors can be a major problem for various parts not functioning properly as well as causing damage to the wiring connection. Thus, it is important to replace faulty parts now!
6. Engine Control Module - Faulty ECM leads to engine stalling or not starting, and check engine lights being on. Replace damaged ECM now!
7. Powertrain Control Module - PCM related issues can hamper the fuel delivery system and engine performance. Find all the Powertrain related parts with us.
8. Diagnostic Tool - You will need high grade diagnostic tools for correction of the OBD error code which is detected. Visit us today to grab amazing deals.

Willing to know some common symptoms of OBD Code P0732? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check Engine Light illuminated (Malfunction indicator lamp)
• Delayed shift or not shifting into 2nd gear
• Transmission slipping
• Loss of fuel economy
• In some cases, there may be performance problems, such as dying when coming to a stop after driving on the freeway and/or misfire-like symptoms

We have listed out some ways which would help you to correct the occurrence of OBD Code P0732. They are mentioned here as follows:

• Refill of Low transmission fluid level
• Dirty transmission fluid to be changed
• Faulty Shift Solenoids Replacement
• Repair or replace Shift Solenoids harness which is open or shorted
• Faulty Shift Solenoids circuit, electrical connection repair/replace

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, Dipstick, Internal Fluid System and many more. Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• 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.

Common Mistakes When Diagnosing the P0732 Code

Oftentimes the PCM sensor and circuit is blamed, and replaced, without checking the circuit as well as neglecting the damaged wiring and connectors. Because there can be several causes for this code, a complete inspection should be carried out in order to avoid repairs that may be unnecessary and more expensive.
