P2198 – Meaning, Causes, Symptoms, & Fixes
Code P2198 Definition O2 Sensor Signal Stuck Rich (Bank 2, Sensor 1) What Does P2198 Mean? Code P2198 is a result of the pre-catalytic converter oxygen sensor detecting a rich air to fuel ratio of the exhaust on bank 2. This ratio is sent to the ECM, which uses this data, along with comparisons to […]
P2196 – Meaning, Causes, Symptoms, & Fixes
Code P2196 Definition O2 Sensor Signal Stuck Rich (Bank 1, Sensor 1) What Does P2196 Mean? Code P2196 is a result of the pre-catalytic converter oxygen sensor detecting a rich air to fuel ratio of the exhaust on bank 1. This ratio is sent to the ECM, which uses this data, along with comparisons to […]
P2197 – Meaning, Causes, Symptoms, & Fixes
Definition of Code P2197 O2 Sensor Signal Stuck Lean- Bank 2 Sensor 1 What Does P2197 Mean? The P2197 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This specified range is characterized by a minimum of 10 cycles per second. This sensor […]
P2195 – Meaning, Causes, Symptoms, & Fixes
Definition of Code P2195 O2 Sensor Signal Stuck Lean- Bank 1 Sensor 1 What Does P2195 Mean? The P2195 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This specified range is characterized by a minimum of 10 cycles per second. This sensor […]
P0031 – Meaning, Causes, Symptoms, & Fixes
Code P0031 Definition HO2S Heater Control Circuit Low (Bank 1, Sensor 1) What Does P0031 Mean? The P0031 code is a result of the bank 1 HO2S1 (pre catalytic converter heated oxygen sensor) heating element having low voltage. Heated O2 sensors have a separate heater inside the sensor to get them to operating temperature quickly. […]
