If the PCM sees an open condition with the signal when the fuel pump isn't activated, P023F may set. Symptoms. Symptoms of a P023F DTC may include: MIL (malfunction indicator lamp) illumination; Fuel pump runs with key off; Small amount of voltage present on FP (fuel pump) voltage supply circuit due to short ; Causes. Potential causes of a ...

2022年6月2日 · The Diagnostic Trouble Code (DTC) will be set if the fuel pump driver control module detects that the fuel pump current is less than 1 A and the fuel pump duty cycle is approximately 30 - 60 % for 1 s.

OBD-II Code P023F is a diagnostic trouble code that indicates an issue in the secondary circuit or an open in the fuel pump. The secondary circuit is responsible for delivering electricity to the fuel pump after it has been powered up.

2020年2月7日 · 如果在燃油泵未启动时 pcm 检测到信号的开路状态，则可能会设置 p023f。 症状. dtc p023f 的症状可能包括： mil（故障指示灯）照明 燃油泵无需钥匙即可工作 由于短路，fp（燃油泵）电压供应电路中存在少量电压. 原因. 原因. p023f 代码的潜在原因包括： 燃油泵继电 ...

2025年1月5日 · The P023F trouble code is a diagnostic trouble code (DTC) that indicates a problem with the fuel pump secondary circuit in a vehicle’s fuel delivery system. Specifically, it signifies an open circuit condition, meaning that the powertrain control module (PCM) has detected that the fuel pump is not receiving the necessary electrical signal to ...

2022年10月18日 · The P023F code is defined as Fuel Pump Secondary Circuit/Open. The powertrain control module (PCM) triggers this code when it detects a problem with the fuel pump or its circuit. The fuel pump relay is responsible for supplying electric current to the fuel pump when it’s activated by the PCM.

When diagnosing a P023F issue, common symptoms serve as important indicators of potential fuel pump circuit problems. One of the key signs to look out for is the illumination of the Malfunction Indicator Lamp (MIL). If you notice the MIL light up on your dashboard, it could be pointing to a fuel pump driver issue related to the P023F trouble code.

2019年4月13日 · Code P023F Description. The Engine Control Module (ECM) provides ignition positive voltage to the coil side of the fuel pump relay. When the ignition switch is first turned ON, the ECM energizes the fuel pump relay, which applies power to the fuel pump.

2024年8月31日 · The P023F: Fuel Pump Secondary Circuit/Open code indicates that there is an open circuit within the fuel pump’s secondary circuit, meaning the circuit is not completing properly. This could be due to a broken wire, faulty relay, or issues with the PCM.

2022年6月2日 · The Diagnostic Trouble Code (DTC) will be set if the fuel pump driver control module detects that the fuel pump current is less than 1 A and the fuel pump duty cycle is approximately 30 - 60 % for 1 s.
