Toyota C2142/42 Code

ECU Malfunction
This sub type is used by the control module to indicate a malfunction in the ECU.

Toyota C2142/42 Code is an error code associated with a transmitter ID2 error. This code is output from the tire pressure warning valve and transmitter when an “ERROR” signal is received three times consecutively, indicating that the inflation pressure is outside the range 0 to 637.5 kPa (0 to 6.48 kgf/cm2, 0 psi to 92.2 psi), the temperature inside the tire is outside the specified range -40 to 120°C (-40 to 248°F), or an error occurs in the tire pressure warning valve and transmitter or the surrounding area. When this happens, the tire pressure warning light is activated. In order to understand the Toyota C2142/42 Code and its associated causes and solutions, it is important to understand the components and systems related to the code. This includes the tire pressure warning valve and transmitter, the tire pressure warning ECU, general memory failure, and ECU malfunction. With this knowledge, we can learn the causes of the code and the solutions for fixing it.

Toyota C2142/42 Code – Causes and Solutions

Cause Solution
Tire pressure warning valve and transmitter Check the valve and transmitter for any signs of damage or malfunction.
Tire pressure warning ECU Replace the ECU and test if the code is resolved.
General Memory Failure Reset the memory, or replace the memory module.
ECU Malfunction Replace the ECU and test if the code is resolved.

Tire pressure warning valve and transmitter

The tire pressure warning valve and transmitter is responsible for sensing the tire pressure and sending the data to the ECU. If the valve and transmitter malfunction, the tire pressure warning light will be triggered. To check for any signs of damage or malfunction, the valve and transmitter must be inspected. If any issues are found, the valve and transmitter must be replaced.

Tire pressure warning ECU

The tire pressure warning ECU is responsible for controlling the tire pressure warning system. If the ECU malfunctions, the tire pressure warning light will be triggered. The ECU should be replaced if any issues are found. After replacing the ECU, it should be tested to make sure the code is resolved.

General Memory Failure

If the code is caused by a general memory failure, the memory must be reset or replaced. The memory should be tested to make sure the code is resolved.

ECU Malfunction

This sub type is used by the control module to indicate a malfunction in the ECU. If the code is caused by an ECU malfunction, the ECU should be replaced. After replacing the ECU, it should be tested to make sure the code is resolved.

Conclusion

In conclusion, the Toyota C2142/42 Code can be caused by a malfunction in the tire pressure warning valve and transmitter, the tire pressure warning ECU, general memory failure, or ECU malfunction. To fix the code, it is important to understand the components and systems related to the code. Solutions for fixing the code include checking the valve and transmitter for any signs of damage or malfunction, replacing the ECU, resetting the memory, or replacing the memory module.
