What is P0733 : Engine Error code Causes Explained
The P0733 engine error code indicates a problem with the transmission’s third gear. This issue can affect vehicle performance and may trigger warning lights on the dashboard. Understanding this code helps drivers identify when professional diagnosis and repair are necessary
How to Identify a DTCs Number
The DTC number P0733 refers to a specific engine error code related to transmission issues, specifically indicating “Gear 3 Incorrect Ratio.”
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.
To identify a DTC like P0733, use an OBD-II scanner connected to the vehicle’s diagnostic port. The onboard computer stores fault codes, and the scanner reads these codes to reveal specific errors like P0733.
Causes of P0733 Error Code:
- Low transmission fluid level:
Insufficient fluid can disrupt proper gear changes, leading to incorrect gear ratios. - Contaminated transmission fluid:
Dirty or burnt transmission fluid affects performance, causing shifting issues. - Faulty transmission speed sensors:
Faulty sensors misinform the PCM about transmission speed, causing gear miscalculations. - Worn transmission clutches or bands:
Worn clutch plates or bands cause slippage, leading to incorrect gear ratios. - Damaged torque converter.
A failina toraue converter disrupts smooth shiftina, triagerina the P0733 code. - Defective transmission solenoids:
Faulty solenoids disrupt hydraulic pressure, affecting gear changes. - Transmission control module (TCM) failure:
A faulty TCM disrupts transmission management, causing shifting issues. - Internal transmission wear.
Worn internal parts, like gears or bearings, cause gear ratio issues.
Risk Level of P0733 Error Code:
The Medium Risk Level of the P0733 engine error code indicates that the vehicle’s transmission is experiencing issues with the third gear ratio, which can affect drivability but is not immediately dangerous.
If this code appears, it’s advisable to diagnose and repair the issue soon to prevent further complications.
