What does P0421 code mean?
The P0421 code means that the powertrain control module is noticing that the catalyst system is not performing as it should during warm up conditions. The powertrain control module uses data received from the upstream and downstream oxygen sensors and compares the two readings given.
What is catalyst efficiency?
The catalyst efficiency monitor verifies the catalytic converter is operating at a high enough efficiency rating to keep exhaust emissions within the predetermined values. The PCM compares the signals from the upstream and downstream oxygen sensors to determine the state of the converter.
What does p0432 mean on engine Bank 2?
The P0432 code indicates that the efficiency for the catalytic converter on engine bank 2 is below efficiency. It may also appear in conjunction with the P0434 code (heated catalyst temperature below threshold for bank 2), or with one or more oxygen sensor codes.
What does the p0432 code on a catalytic converter mean?
It may also appear in conjunction with the P0434 code (heated catalyst temperature below threshold for bank 2), or with one or more oxygen sensor codes. The P0432 code means that your catalytic converter for bank 2 of your engine is performing below what it should be.
What are the symptoms of a p0432 DTC?
Bank 2 is the side of the engine that does *not* contain cylinder #1. Symptoms of a P0432 DTC may include: Increased tailpipe emissions MIL (Malfunction Indicator Lamp) illumination
How much does it cost to diagnose a p0432 Jeep code?
The cost to diagnose the P0432 JEEP code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? When is the code detected?
