P0942 OBD Error Code: Problem & Solutions

OBD Code P0942 - Hydraulic Pressure Unit

<<See All OBD Codes

The trouble code P0942 can be elucidated as Hydraulic Pressure Unit. The transmission control system electronically controls the line pressure. It is then measured by the line pressure sensor. The line pressure which is desired would be compared to the actual line pressure. It would then be regulated by electronically changing the duty cycle of the pressure control solenoid. The line pressure would be calculated by the transmission control system as it is based upon the inputs from the transmission as well as from the car engine. A calculated torque input to the transmission is used as the main input to the desired line pressure calculation and is known as torque based line pressure. The transmission control module would then monitor the hydraulic pressure sensor. The TCM sets the OBDII code when the hydraulic pressure sensor would not be as per the factory specifications.

Easy Diagnosis Of Engine Error OBD Code P0942

Here are some steps which you should follow in order to diagnose this fault code:

 

As an initial step the mechanic will carefully inspect the vehicle with the help of a scanner. After this, the technician will connect a scanner to the diagnostic code so that he can recover all the codes and freeze frame data. Note down this information as it can clearly help for further diagnosis. The mechanic will also inspect the shift solenoid to find if it is disconnected or if any other faults persist. After careful inspection, he will reset the code and test drive your vehicle to check for reappearance of the codes. He will know that an intermittent condition persist, if the code does not return instantly. But if the error code returns quickly, the vehicle is test driven, and then he has to inspect the transmission fluid.

 

Once the fluid is checked for appropriate level, then every other components like wires and connectors have to be checked for possible damages. If any of the component is damaged, the mechanic will replace them quickly. Most often, whenever the mechanic carries out any repair work, he will reset the code and test drive your car, to check if the codes return immediately. This can preferably help the mechanic to know what caused this error code in the vehicle.

 

Common Mistakes When Diagnosing The P0942 Code
