Details of the Dodge p0430 OBD Code

Dodge P0430 indicates a catalyst system efficiency below threshold in bank 2.

Dodge OBD code P0430 means that the catalyst system efficiency is below the threshold for the bank 2 catalytic converter.

This code is triggered by the Engine Control Module (ECM) based on the signals from the oxygen sensors before and after the catalytic converter on bank 2. The ECM compares the readings from these sensors to determine if the catalytic converter is functioning properly to reduce emissions.

If the efficiency is below the specified threshold, the P0430 trouble code is set.

Mechanic’s Tech Notes

Detailed information on diagnosing and repairing Dodge fault code P0430 related to catalyst system efficiency below threshold.

To diagnose and fix OBDII code P0430 in a Dodge, start by checking the oxygen sensor (bank 2 sensor 1) voltage readings with a voltmeter.

Compare the readings to specifications to determine sensor health.

Next, inspect the catalytic converter for damage or clogging.

Use a scan tool to monitor live data and ensure the catalytic converter efficiency is within the expected range.

If the converter is faulty, replacement may be necessary.

Additionally, check for exhaust leaks before the converter that could skew sensor readings.

Clear the code after repairs and perform a road test to verify the fix.
