SPN 247 FMI 1 – MCM Engine Hours Data lower than expected Fault Code (Symptoms, Causes & Fix)

The SPN 247 FMI 1 fault code indicates that the Engine Control Module (ECM) has detected that the engine hours data is lower than expected. This diesel engine fault code suggests a discrepancy in the engine hours reading, which could be due to issues with the ECM, wiring, or sensor inputs.What SPN 247 FMI 1 MeansThe SPN 247 FMI 1 fault code represents a situation where the ECM is receiving engine read more

SPN 247 FMI 0 – MCM Engine Hours Data higher than expected Fault Code (Symptoms, Causes & Fix)

The SPN 247 FMI 0 fault code indicates that the Engine Control Module (ECM) has detected engine hours data that is higher than expected. This diesel engine fault code suggests a discrepancy in the recorded engine hours, which could be due to an issue with the ECM or related components. Understanding this diagnostic trouble code is crucial for accurate troubleshooting and repair. What SPN 247 FMI read more

SPN 191 FMI 19 – J1939 Transmission Output Shaft Speed Signal is erratic Fault Code (Symptoms, Causes & Fix)

The SPN 191 FMI 19 fault code is a diesel engine diagnostic trouble code indicating that the J1939 transmission output shaft speed signal is erratic. This code is logged when the Engine Control Module (ECM) detects inconsistent or fluctuating signals from the transmission output shaft speed sensor, which can affect the vehicle's shifting and performance.What SPN 191 FMI 19 MeansThe SPN 191 FMI 19 read more

SPN 191 FMI 13 – J1939 Transmission Output Shaft Speed Signal is missing or not available Fault Code (Symptoms, Causes & Fix)

The SPN 191 FMI 13 fault code indicates that the J1939 Transmission Output Shaft Speed Signal is missing or not available. This diesel engine fault code suggests a communication issue between the transmission output speed sensor and the Engine Control Module (ECM). The ECM relies on this signal to monitor and control transmission functions effectively. What SPN 191 FMI 13 Means When the SPN 191 F read more

SPN 191 FMI 9 – J1939 ETC1 Message is missing Fault Code (Symptoms, Causes & Fix)

The SPN 191 FMI 9 fault code indicates a missing J1939 ETC1 message, which is a critical communication signal between the Engine Control Module (ECM) and other components on the network. This diesel engine fault code suggests that the ECM is not receiving the expected data from the J1939 data link, potentially affecting engine performance and diagnostics.What SPN 191 FMI 9 MeansSPN 191 FMI 9 repre read more

SPN 188 FMI 31 – Idle Speed Out of Range Fault Code (Symptoms, Causes & Fix)

The SPN 188 FMI 31 fault code is a diesel engine diagnostic trouble code indicating that the engine's idle speed is out of the expected range. This code is triggered when the Engine Control Module (ECM) detects that the idle speed is not within the specified parameters, which could be due to various mechanical or electrical issues affecting the engine idle control system.What SPN 188 FMI 31 MeansT read more

SPN 175 FMI 20 – Engine Oil Temperature Sensor Signal Not Plausible Fault Code (Symptoms, Causes & Fix)

The SPN 175 FMI 20 fault code is a diesel engine fault code indicating that the engine oil temperature sensor signal is not plausible. This diagnostic trouble code suggests that the Engine Control Module (ECM) is receiving a signal from the engine oil temperature sensor that does not align with expected parameters, potentially due to electrical issues or sensor failure.What SPN 175 FMI 20 MeansThe read more

SPN 175 FMI 18 – Oil Temperature Sensor, Minimum Temperature Plausibility Fault Code (Symptoms, Causes & Fix)

The SPN 175 FMI 18 fault code is a diesel engine fault code indicating an issue with the oil temperature sensor, specifically a minimum temperature plausibility error. This diagnostic trouble code suggests that the Engine Control Module (ECM) is detecting an implausibly low oil temperature reading, which could be due to sensor malfunction or electrical issues.What SPN 175 FMI 18 MeansWhen the SPN read more

SPN 175 FMI 15 – Oil Temperature High Pre-Warning Fault Code (Symptoms, Causes & Fix)

The SPN 175 FMI 15 fault code is a diesel engine diagnostic trouble code indicating an oil temperature high pre-warning condition. This code is triggered when the Engine Control Module (ECM) detects that the oil temperature is approaching a critical level, potentially leading to engine damage if not addressed. Understanding this fault code is crucial for maintaining engine health and preventing co read more

SPN 175 FMI 4 – Engine Oil Temperature Circuit Failed Low Fault Code (Symptoms, Causes & Fix)

The SPN 175 FMI 4 fault code is a diesel engine fault code indicating that the engine oil temperature circuit has failed low. This diagnostic trouble code suggests that the Engine Control Module (ECM) is receiving a signal from the engine oil temperature sensor that is lower than expected, which could be due to an electrical issue within the sensor circuit.What SPN 175 FMI 4 MeansThe SPN 175 FMI 4 read more
