If you are the owner of a Volvo and you have recently received the ECM-P017400 code, you may be wondering what it means and how to fix it. This Volvo ECM-P017400 Code is defined as System Too Lean (Bank 2). This code is generated when the Engine Control Module (ECM) receives information from the heated oxygen sensor about fuel/air mixture in different load areas, and if it registers that the fuel/air mixture deviates too much from target lambda, the diagnostic trouble code is generated. Common causes of the ECM-P017400 Code include too high ethanol content in fuel, incorrectly installed/damaged oil dipstick (air leakage), air leakage intake manifold, air leakage, exhaust pipe, low fuel pressure, and damaged mass air flow sensor.
Causes and Solutions for Volvo ECM-P017400 Code
| Cause | Solution |
|---|---|
| Too high ethanol content in fuel | Use a fuel with a lower ethanol content. |
| Incorrectly installed/damaged oil dipstick (air leakage) | Replace or repair the oil dipstick. |
| Air leakage intake manifold | Check for any leaks in the intake manifold, and repair as needed. |
| Air leakage, exhaust pipe | Check for any leaks in the exhaust pipe, and repair as needed. |
| Low fuel pressure | Check the fuel pressure and replace the fuel pump if needed. |
| Damaged mass air flow sensor | Replace the mass air flow sensor. |
If you own a Volvo and are presented with the ECM-P017400 Code, you may be confused and unsure of what this code means. This code stands for System Too Lean (Bank 2) and it is generated when the Engine Control Module (ECM) receives information from the heated oxygen sensor about fuel/air mixture in different load areas. If the ECM registers that the fuel/air mixture deviates too much from target lambda, this diagnostic trouble code is generated. Common causes of this code include too high ethanol content in fuel, incorrectly installed/damaged oil dipstick (air leakage), air leakage intake manifold, air leakage, exhaust pipe, low fuel pressure, and damaged mass air flow sensor. To resolve this issue, use the table above for helpful causes and solutions.
Too High Ethanol Content in Fuel
One of the major causes of the Volvo ECM-P017400 Code is too high ethanol content in fuel. To fix this problem, use a fuel with a lower ethanol content. This should help to resolve the issue and get your Volvo back on the road.
Incorrectly Installed/Damaged Oil Dipstick (Air Leakage)
Another common cause of the ECM-P017400 code is an incorrectly installed/damaged oil dipstick. If this is the case, it is best to replace or repair the oil dipstick. This should help to fix the problem and get your Volvo running again.
Air Leakage Intake Manifold
If there is an air leakage in the intake manifold, this could also be the cause of the ECM-P017400 code. To fix this issue, check for any leaks in the intake manifold, and repair as needed.
Air Leakage, Exhaust Pipe
In some cases, the ECM-P017400 code could be caused by an air leakage in the exhaust pipe. To resolve this issue, check for any leaks in the exhaust pipe and repair as needed.
Low Fuel Pressure
Low fuel pressure could also be the cause of the ECM-P017400 code. To fix this problem, check the fuel pressure and replace the fuel pump if needed.
Damaged Mass Air Flow Sensor
The last potential cause of the ECM-P017400 code is a damaged mass air flow sensor. To fix this issue, you should replace the mass air flow sensor.
Conclusion
In conclusion, the Volvo ECM-P017400 Code is generated when the Engine Control Module (ECM) receives information from the heated oxygen sensor about fuel/air mixture in different load areas. If the ECM registers that the fuel/air mixture deviates too much from target lambda, this diagnostic trouble code is generated. Common causes of this code include too high ethanol content in fuel, incorrectly installed/damaged oil dipstick (air leakage), air leakage intake manifold, air leakage, exhaust pipe, low fuel pressure, and damaged mass air flow sensor. If you own a Volvo and are presented with this code, use the table above for helpful causes and solutions.
