September 16, 2020 P0170 Code: Fuel Trim (Bank 1)To ensure the air-fuel ratio of the mixture burns as efficiently as possible, the powertrain control module (PCM) tweaks the vehicle’s fuel trim over short and long periods. If the computer cannot properly adjust the air-fuel mix, it will log the diagnostic trouble code P0170.
What Does the P0170 Code Mean?
September 10, 2020 P2187 Code: System too Lean at Idle (Bank 1)The P2187 code is one of the more ambiguous codes that your vehicle’s onboard diagnostics system can trigger. It’s important to approach diagnosis and repair correctly, so you don’t end up wasting time, energy, and money. This guide will help you learn more about code P2187, including its common causes, September 03, 2020 P2196 Code: O2 Sensor Signal Biased/Stuck Rich (Bank 1, Sensor 1)Oxygen sensors are essential to maintaining the ideal air/fuel mixture in your engine. They tell the powertrain control module (PCM) the amount of oxygen in the exhaust stream. Knowing the ratio of fuel to air enables the PCM to make any necessary changes to the engine’s air/fuel mixture.
October 27, 2020 P0104 Code: Mass Air Flow (MAF) “A” Circuit Intermittent / ErraticYour vehicle is equipped with various sensors that are crucial to its operation. A mass air flow (MAF) sensor, for example, is one of the key components of the engine’s fuel injection system. It measures the amount of air entering the engine so that the powertrain control module (PCM) would October 09, 2019 Symptoms of a Bad Mass Air Flow SensorMany cars use a mass air flow (MAF) sensor to measure the amount of air entering the engine. When the device goes bad, it can lead to various symptoms, ranging from an illuminated check engine light to rough running and misfiring.
