Hyundai P0420 Bank 1

Catalyst system efficiency below threshold bank 1.

Hyundai p0420 bank 1. P0420 hyundai description the engine control module ecm monitors the switching frequency ratio of heated oxygen sensors 1 front o2 sensor and heated oxygen sensors 2 rear o2 sensor. The upstream oxygen sensor located before the cat and the downstream oxygen sensor. P0420 is a diagnostic trouble code dtc for catalyst system efficiency below threshold bank 1. Here is a tutorial on how to fix code p0420 catalyst system efficiency below threshold bank 1 how to diagnose and fix a catalytic converter and what to look.

The p0420 code is stored in memory when the ecu detects a low efficiency in the catalyst system for bank number 1 the bank of cylinders where cylinder number 1 is located. Most auto repairs shops charge between 75 and 150 per hour. In fact it would be a good idea to test each oxygen o2 sensor while you re at it. What does code p0420 mean.

Hyundai code p0420 definition. The ecu determines the efficiency of the catalytic converter cat using two sensors. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The auto repair labor rates vary by location your vehicle s make and model and even your engine type.

The obd2 code. We recommend torque pro. What does p0420 mean for your hyundai. 1 0 the cost of diagnosing the p0420 hyundai code is 1 0 hour of labor.

Obd ii fault code p0420 is a generic code that is defined as catalyst system efficiency below threshold bank 1 and is set when the pcm powertrain control module detects a condition that indicates that the catalytic converter on bank 1 is operating below the minimum allowable efficiency threshold. P0420 description the engine control module monitors the switching frequency ratio of heated oxygen sensors 1 front o2 sensor and heated oxygen sensors 2 rear o2 sensor a three way catalyst converter manifold with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. The function of the catalytic converter is to break down harmful pollutants that are created by your hyundai during the combustion cycle and convert them into harmless gases. Code p0420 indicates that the catalytic converter is not functioning efficiently therefore.
