  • The automobile fault code P2187 can be caused by various factors.
  • These include intake air leaks, a faulty front heated oxygen sensor, ignition misfiring, faulty fuel injectors, incorrect fuel pressure, lack of fuel, a faulty Mass Air Flow (MAF) sensor, and an incorrect Positive Crankcase Ventilation (PCV) hose connection.
  • It is important to identify the specific cause of the fault code to effectively address the issue and prevent further damage to the vehicle.

To fix the p2187 automobile fault code, check the possible causes and inspect related components for damage or corrosion.

  • To fix the automobile fault code p2187, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The fault code P2187 indicates a lean fuel mixture in the engine. The diagnosis involves checking the fuel pressure, fuel injectors, and vacuum leaks. The estimated repair time for this fault code is 1.0 hour.

The cost of fixing this issue varies between $75 and $150 per hour, depending on the auto repair shop.

The total cost will depend on the severity of the problem and the parts that need to be replaced.

The P2187 code indicates a lean condition in the airfuel mixture at idle.

The Powertrain Control Module (PCM) monitors the HO2S signal voltage and adjusts fuel delivery based on it. The PCM adds fuel when the HO2S signal indicates a lean condition.

The DTC is set when the fuel trim values reach excessive levels due to a lean condition. The ideal fuel trim value is around 0%.

The P2187 code is relevant to fuel trim.

What are the possible causes of the P2187 fault code in an automobile?

If you’re experiencing a hard-to-start engine when cold and the engine light is on, the P2187 fault code may be the culprit. This code is often caused by intake air leaks, faulty front heated oxygen sensors, ignition misfiring, faulty fuel injectors, incorrect fuel pressure, lack of fuel, faulty Mass Air Flow (MAF) sensors, or incorrect Positive Crankcase Ventilation (PCV) hose connections. To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for damaged components or corroded connector pins.
