Simply stated, a stored code P0189 means that the powertrain control module (PCM) has detected a voltage signal from the fuel temperature sensor (or circuit) that is intermittent or erratic. "B" refers to an area of circuitry as opposed to a particular circuit or component.

The P0189 code indicates a problem with the fuel temperature sensor 'B' circuit in the vehicle. This sensor is responsible for measuring the temperature of the fuel in the fuel tank and transmitting this information to the engine control module (ECM).

2025年2月2日 · What does the P0189 code mean? The P0189 code is a diagnostic trouble code (DTC) that signifies an intermittent issue with the fuel temperature sensor B circuit in your vehicle. This sensor plays a vital role by monitoring the temperature of the fuel before it …

The fuel temperature sensor ‘2’ circuit intermittent problem is referred to in the DTC code P0189. This code is connected to OBD II, a system that constantly controls various aspects of the vehicle’s performance, fuel management, and emissions.

P0189 is a diagnostic trouble code (DTC) for "Fuel Temperature Sensor "B" Circuit Intermittent". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

What is OBD-II Code P0189 – Fuel Temperature Sensor B Circuit Intermittent? The P0189 code relates to the fuel temperature sensor in a vehicle’s fuel system. The fuel temperature sensor is responsible for monitoring the fuel temperature and sending this data to the PCM.

What does OBD-II fault code P0189 mean? OBD-II Code Powertrain Control Module (PCM) failure is defined as a Fuel Temperature Sensor "B" Circuit Intermittent. The Fuel Temperature …

2016年6月3日 · Specifically, if the ECM detects a temperature change in excess of ±10 °C (±18 °F) / 100 ms, it interprets this as an intermittent circuit fault, setting DTC P0189 – “Fuel Temperature Sensor “B” Circuit Intermittent.”

2020年6月14日 · Code P0189 Description. The fuel tank temperature sensor is used to detect the fuel temperature inside the fuel tank. The sensor modifies a voltage signal from the Engine Control Module (ECM). The modified signal returns to the ECM as the fuel temperature input. The sensor uses a thermistor which is sensitive to the change in temperature.

2023年8月3日 · The OBD-II diagnostic trouble code P0189 pertains to the “Fuel Temperature Sensor B Circuit Intermittent” problem. This code indicates that the fuel temperature sensor B is sending intermittent signals to the engine control module (ECM), leading to inconsistent fuel temperature readings.
