P0430

Hi there. If you are getting this code (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) along with a loss of power, it usually means that the catalytic converter is failing. When it fails internally it begins to clog the exhaust which will cause the lack of...

Your vehicle has groups of sensors that take readings and report back to the engine computer to make adjustments, or report an error; in this case, we're dealing with oxygen and/or air/fuel-ratio sensors. The code P0430 indicates a failure in...

Diagnostic Trouble Code P0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) means that the ECU is detecting below threshold performance from the catalytic converter. The ECU monitors the catalytic converter closely and when a low performance threshold is detected the Check Engine Light will be displayed...

Hi there. When the codes P0420 (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) and P0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) come up, usually the catalytic converter has failed, but before you determine if you need to replace the catalytic converter, consider checking the following: A damaged or failed oxygen sensor...

The Check Engine Light on for code P0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) is for the right (passenger side) O2 sensor indicating a bad catalyst on the passenger side or right side of the vehicle. Before replacing the catalyst (https://www.yourmechanic.com/services/catalytic-converter-replacement), check all the engine...

To answer the question will I pass emissions if P0305 is fixed: if the two other codes are cleared after repairs are done for the P0305 code (https://www.yourmechanic.com/article/p0305-obd-ii-trouble-code-cylinder-5-misfire-detected-by-jay-safford) and they do not come back then you may pass emissions. The...

A P0430 code indicates the catalyst efficiency has fallen off. If there are no other codes indicating misfires and if the check engine light is not blinking, you should be OK to drive your car. If you have trouble scheduling...

Hello. To address the converter, there is no cure for a failing converter. In many cases, these cleaners will clean out some of the build up in the converter but definitely not all of it. You will end up needing...

Hello. The camshaft position sensor is located on the passenger side of the engine bay, on the cylinder head near the coolant reservoir tank. The reservoir tank needs to be removed in order to access it. If you need help...

Hi, thanks for writing in. This P0430 code (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) is for the bank B or driver side converter or the O2 sensor after the converter. The code will need to be diagnosed to isolate the problem to the sensor or...

The most common causes of Diagnostic trouble code P0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) setting are a faulty catalytic converter, engine misfire, fuel injector leakage, engine mechanical damage, faulty oxygen sensor outputs and exhaust leaks. Additionally, in your circumstance, malfunctions in the charge air...

Diagnostic Trouble Code P0017 (https://www.yourmechanic.com/article/p0079-obd-ii-trouble-code-crankshaft-position-camshaft-position-correlation-bank-1-sensor-b-by-jay-safford) has many causes other than a failed position sensor. For example, the valve timing could be off if the timing chain has jumped, there could be oil flow problems to the phaser from incorrect oil...

Hi there. Typically when you get this code it is due to a failing converter. You car has two of them, one for each side of the engine, and when they go bad anf no longer function right them this...

Hi there. The code p0403 (https://www.yourmechanic.com/article/p0403-obd-ii-trouble-code-exhaust-gas-recirculation-circuit-malfunction-by-jay-safford) is for the EGR circuit that shows it has malfunctioned. The code p0430 (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) is for the catalytic converter showing that its below threshold. Check the harness to the EGR and make sure that...

Hello and thank you for contacting YourMechanic. Check for any exhaust leaks in the exhaust system. If there is a slight ticking sound or a light to loud rumble, then there is a possible exhaust leak. Check the O2 sensors...

Hello and thank you for contacting Your Mechanic. The code P0430 means that the catalyst system efficiency is below threshold on bank 2. This is in relation to the catalytic converter not functioning correctly, but this code will not make...

The code is meant to indicate your catalytic converter is not performing up to par with the EPA (environmental protection agency) standards. Your car uses the oxygen sensors (https://www.yourmechanic.com/services/oxygen-sensor-replacement) to monitor the catalytic converter (cat) efficiency. There is an O2...

Hello. This issue can be caused by a failing catalytic converter (https://www.yourmechanic.com/services/catalytic-converter-replacement) or by a bad oxygen sensor (https://www.yourmechanic.com/services/oxygen-sensor-replacement). As for driving the vehicle, if it is not lacking any power then it should be fine to drive. The only...

Hi, thanks for writing in. This code (https://www.yourmechanic.com/article/p0430-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-2-by-spencer-clayton) is for the O2 sensor after the catalyst for the driver side. You will need to have the code diagnosed to see if the sensor is working okay or the catalyst is...

Hello. This code is also related to the catalytic converter (https://www.yourmechanic.com/services/catalytic-converter-replacement) not working properly. This can also happen when the ground wires connected to the O2 sensors (https://www.yourmechanic.com/services/oxygen-sensor-replacement) are not properly hooked up causing them to send erroneous info to...
