What does the p0430 OBD-II trouble code mean?
P0430 code definition P0430 is a generic diagnostic trouble code that indicates a malfunction within the catalyst system. It may been seen with misfire codes and oxygen sensor codes. What the P0430 code means
Why is my OBD2 not communicating with my PCM?
Key off and use a good 10 megaohm impedance ohmmeter to test the pin 5 to ground. If no ground the circuit is broken somewhere between the OBD2 connector and the PCM If the ground is good then it is either a bad connection on pin 2 back to the PCM or a Bad PCM itself, which I suspect is the problem.
What causes a p04030 code on a freeze frame?
Performs a road test under similar conditions to the freeze frame data to confirm the problem Mistakes can be made easily when a mechanical problem is overlooked as the cause for the P04030 code such as a leaking fuel injector or a leaking head gasket.
What is the OBD-II trouble code for catalyst?
P0430 OBD-II Trouble Code: Catalyst System Efficiency Below Threshold (Bank 2) Cost of diagnosing the P0430 code. P0430 is a diagnostic trouble code (DTC) for “Catalyst System Efficiency Below Threshold (Bank 2)”.
What does the O2 sensor code p0430 mean?
Code P0430 Common Diagnosis Mistakes Often times this code is thought to be a faulty O2 sensor or A/F Sensor; while this is a possibility, the most common problem is a faulty catalytic converter. Do not overlook other codes that are paired along with P0420.
Can a catalytic converter be replaced with a p0430 code?
Replacing the oxygen (O2) sensors may sometimes fix the code, but in most cases, the catalytic convert needs to be replaced to fix the problem. If the P0430 code is combined with other codes, try fixing the other codes first. User Submitted Video What does this mean? Cost of diagnosing the P0430 code Labor: 1.0
When does p0430 Dodge catalyst efficiency Bank 2 malfunction?
As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. Need more information on how to fix the P0430 DODGE code?
Why does my Sentra have a p0430 error message?
Today I had a 2001 Sentra with four sensors even though it was just a four-cylinder. The car had a P0430 error message for the Bank Two converter only. The rear oxygen sensor wire connectors were right next to each other under the hood, so I just jumpered the two signal wires together and ran the drive cycle. Problem gone.
What causes a P030 code on a catalytic converter?
That’s how important the converter is. An upstream leak in the exhaust system, such as a crack in the exhaust manifold or a loose header pipe at the manifold that allows air to enter and confuse the upstream sensor. One possible cause of the P030 code is a damaged or failing oxygen sensor.

Which is the mirror image of the p0430 code?
The P0430 code’s mirror image is P0420, which applies to the converter on bank 1. As was mentioned, bank 1 and bank 2 simply refer to the different sides of the engine.
What causes the p0430 code to be thrown?
Oxygen Sensor – The P0430 codes is thrown when the oxygen sensors on both sides of the exhaust have very similar readings. When the oxygen sensor is bad, it can cause a false reading and trigger the code.

What does P0420 mean on a catalytic converter?
Often times this code is thought to be a faulty O2 sensor or A/F Sensor; while this is a possibility, the most common problem is a faulty catalytic converter. Do not overlook other codes that are paired along with P0420.
What does the p0430 do on a Captiva?
Your Captiva has at least two oxygen sensors, one before and after the catalytic converter. Among the many jobs that oxygen sensors have is they have to measure the emissions levels coming in and out of the converter. P0430 means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading.
