What does the p0430 Nissan Engine Control Module do?
P0430 Nissan 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). A three way catalyst converter (Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2.
What causes the O2 sensor to show the code po420?
Rich or lean mixtures can damage the catalytic converter, and when the catalytic converter is damaged/filled with fuel, the efficiency will be low, and the rear O2 sensor will see that and show the trigger the code Po420.
Why does my Nissan Altima have a bad O2 sensor?

What does the p0328 code mean on a knock sensor?
A P0328 code is a generic DTC, thus it applies to all makes of vehicles, and refers to a high output voltage of the knock sensor. In many cases, this means the voltage is above 4.5V but that specific value depends on the specific make and model of vehicle. This code refers to the sensor on bank #1.
What does the DTC code p0328 stand for?
A P0328 code is a generic DTC, thus it applies to all makes of vehicles, and refers to a high output voltage of the knock sensor.
What to do if your engine light says p0430?
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. What does this mean? Cost of diagnosing the P0430 NISSAN code Labor: 1.0
When is the p1148 Nissan code detected?
Most auto repairs shops charge between $75 and $150 per hour. When is the P1148 NISSAN code detected? The closed loop control function for bank 1 does not operate even when vehicle is driving in the specified condition, the closed loop control function for bank 2 does not operate even when vehicle is driving in the specified condition.
What causes the p0430 trouble code on a Nissan Frontier?
There are many things that can cause the P0430 trouble code in your Frontier. Here are the most common ones. 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 p0430 mean on a catalytic converter?
P0430 means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading. The upstream and downstream oxygen sensors should show different readings. The computer wants to see that the catalytic converter has scrubbed exhaust emissions.
What does p0430 mean on a Chevy Tahoe?
P0430 means that the Oxygen sensor downstream of the catalytic converter is registering an improper reading. The upstream and downstream oxygen sensors should show different readings.
What does the OBD2 code on a Nissan Frontier mean?
P0430 technically stands for: One of the most common trouble codes with all Nissan vehicles is the P0430. This code number references a number that is given to you when you plug your Nissan Frontier into a OBD2 scanner. It doesn’t matter which model you have, this OBDII code (1996 models and newer) has the same meaning for all of them.
