Q: jeep it threw a p0420 and a p2096 code

Diagnostic Trouble Code P0420除氧气传感器故障外，还有许多潜在原因。您不能使用诊断故障代码来确定氧气传感器是否不良。为了确定传感器实际上是否不良，必须在汽车范围上测量和评估氧气传感器输出。如果机械师没有在汽车范围上评估传感器输出，他或她只是猜测需要更换传感器。由于故障代码迅速返回，这意味着传感器没有错，或者充其量只是问题的“部分”。如果没有进行测试，现在就不可能知道。P0420can be caused by a damaged muffler or leaks in the muffler, damaged exhaust manifold or leaks in the exhaust manifold, damaged exhaust pipe or exhaust pipe leaks, misfiring in the engine, oil contamination in catalytic converter, a faulty catalytic converter, a faulty engine coolant temperature sensor, faulty front oxygen sensor, faulty rear oxygen sensor, damaged oxygen sensor wiring, oxygen sensor wiring that is not properly connected, damaged oxygen sensor connectors, a fuel injector that is leaking, fuel pressure that is high, and other causes. Diagnostic Trouble Code P2096 is generally caused by exhaust leaks, clogged injectors, or an intake vacuum leak.
