P0087 KIA Code - Fuel Rail/System Pressure Too Low
Quick Answer
This fault code is stored in the Engine Control Module (ECM) when the fuel pressure is not as expected. Common causes include Faulty fuel pressure sensor, Faulty fuel pump, Fuel pressure sensor harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0087 KIA Description
A number of issues may cause this fault code to be set such as a faulty fuel rail pressure sensor, a mechanical fault with the inlet metering valve or rail pressure control solenoid could cause the valve to become stuck. An electrical fault such as an open circuit in the inlet metering valve or fuel pressure control solenoid on a system with a normally closed valve will also cause this situation. A short circuit on the control wire of a normally open inlet metering valve will also cause this fault.
A fault in the fuel injector return system causes the fuel pressure to be lower than expected. This causes fuel from the high-pressure circuit to be leaked back to the low-pressure circuit. A faulty maximum pressure relief valve will also cause this situation.
The high-pressure pump should also be tested to ensure it is capable of delivering the required volume of fuel.
What are the Possible Causes of the DTC P0087 KIA?
- Faulty fuel pressure sensor
- Faulty fuel pump
- Fuel pressure sensor harness is open or shorted
- Fuel pressure sensor electrical circuit poor connection
- Blocked fuel filter
- Fuel line restricted
- Faulty fuel pressure regulator

Repairs may include replacing the fuel pump, fuel filter, or fuel pressure sensor, fixing fuel line leaks, or cleaning out contaminated fuel.
6. How can I diagnose the cause of P0087 in my Kia?
Use an OBDII scanner to confirm the code, inspect the fuel system components, and test fuel pressure with a gauge to identify the faulty part.
7. Is replacing the fuel pump always necessary for P0087?
No, the issue could be with the fuel filter, pressure sensor, or fuel lines, so proper diagnosis is essential before replacing the pump.
8. Can bad fuel cause the P0087 code in a Kia?
Yes, contaminated or poor-quality fuel can clog the fuel system and reduce pressure, triggering the P0087 code.
