Urgency and Severity The P220B code, indicating an issue with the NOx sensor supply voltage circuit, is of moderate severity. While it does not typically require immediate action, it should not be ignored for extended periods. In our workshop, we've seen the P220B code pop up frequently across various European car makes, particularly in Audi,

Introduction and Urgency Assessment The P220A diagnostic trouble code (DTC) indicates a problem with the NOx sensor supply voltage circuit for Bank 1 Sensor 1. This code is specific to vehicles equipped with NOx sensors, typically found in diesel engines and some newer gasoline engines with advanced emissions control systems. In our workshop, we've seen

Urgency and Drivability P2197 is not an immediately critical issue, but should be addressed promptly to prevent potential damage to the catalytic converter or decreased fuel efficiency. The vehicle can typically be driven safely for short distances, but prolonged operation may lead to more severe problems. In our workshop, we've seen the P2197 code pop

What is Code P2195? OBD-II trouble code P2195 is defined as "O2 Sensor Signal Stuck Lean (Bank 1, Sensor 1)". This is a generic powertrain code that applies to most vehicles equipped with OBD-II, including those made by Ford, GM, Chrysler, Toyota, Honda, Hyundai, etc. In our workshop, we've seen the P2195 code pop up

What is OBD-II Code P2188? OBD-II diagnostic trouble code (DTC) P2188 stands for "Fuel Control System 'A' Too Rich at Idle (Bank 1)". This means the engine control module (ECM) has detected that the air-fuel mixture is too rich (too much fuel compared to air) at idle in bank 1 of the engine. Based on

What is P2187 and How Urgent Is It? P2187 is a diagnostic trouble code (DTC) that indicates the engine control module (ECM) has detected a lean air-fuel mixture at idle in bank 1 of the engine. In other words, there is too much air and not enough fuel at idle conditions. In our workshop, we've

What Does P2178 Mean? Diagnostic trouble code (DTC) P2178 indicates that the engine control module (ECM) has detected that the air-fuel mixture is too rich (too much fuel) when the engine is off idle on bank 1. Bank 1 refers to the side of the engine that contains cylinder #1. In our workshop, we've frequently

What is Code P2177? OBD-II diagnostic trouble code (DTC) P2177 stands for "System Too Lean Off Idle (Bank 1)". This generic powertrain code indicates that the engine control module (ECM) has detected that the air-fuel mixture is too lean (too much air/not enough fuel) in the engine's Bank 1 while off idle. In our workshop,

Understanding the P2138 Throttle Position Sensor Code The P2138 is a generic OBD-II trouble code that indicates a problem with the throttle/accelerator pedal position sensor circuit. This code is triggered when the engine control module (ECM) detects an abnormal voltage signal from the throttle position (TP) sensor and/or accelerator pedal position (APP) sensor that doesn't

What is Code P2135? P2135 is a generic powertrain diagnostic trouble code that stands for "Throttle/Pedal Position Sensor/Switch A / B Voltage Correlation". This means the engine control module (ECM) has detected that the voltage signals from the throttle position (TP) sensor and/or accelerator pedal position (APP) sensor do not correlate with each other as
