The P2087 code is an OBD-II diagnostic trouble code that signifies an issue with the Exhaust Gas Temperature (EGT) sensor circuit. This code indicates that the engine control module (PCM) has detected an intermittent signal from the EGT sensor, which measures the temperature of the exhaust gases entering and exiting the Selective Catalytic Reduction (SCR) system.
What Does the P2087 Code Mean?
The P2087 code specifically relates to the Exhaust Gas Temperature Sensor circuit. When the PCM identifies an implausible signal from the EGT sensor, it triggers this code to be stored in the vehicle’s onboard diagnostic system. This can lead to decreased engine performance and may affect the efficiency of the emission control system.
What Causes the P2087 Code?
Several factors can lead to the P2087 code being triggered, including:
- Exhaust Gas Temperature (EGT) sensor failure
- Powertrain Control Module (PCM) failure
- Wiring issues related to the EGT sensor
What Are the Symptoms of the P2087 Code?
Symptoms associated with the P2087 code can include:
- Decreased engine performance
It is important to note that while these symptoms may not be immediately dangerous, they can lead to more serious issues if not addressed promptly.
How Serious Is the P2087 Code?
The P2087 code is classified as a moderate severity issue. Although it may not pose an immediate threat to the vehicle’s safety or functionality, it is advisable to have it diagnosed and repaired within a reasonable timeframe to ensure optimal vehicle performance and prevent further complications.
How to Diagnose the P2087 Code
Diagnosing the P2087 code typically involves the following steps:
- Using an OBD-II scanner to confirm the presence of the P2087 code.
- Checking the EGT sensor and its wiring for any visible damage or corrosion.
- Testing the EGT sensor to ensure it is functioning within specifications.
- Inspecting the Powertrain Control Module (PCM) for any faults.
Common Repairs for the P2087 Code
Common repairs that may be needed to resolve the P2087 code include:
- Replacing the Exhaust Gas Temperature (EGT) sensor.
- Repairing or replacing damaged wiring or connectors related to the EGT sensor.
- In some cases, replacing the Powertrain Control Module (PCM) if it is determined to be faulty.
How Much Does It Cost to Fix the P2087 Code?
The cost to repair the P2087 code can vary significantly based on the underlying cause of the issue. On average, repairs may range from $100 to $600, depending on whether you need to replace the EGT sensor, repair wiring, or replace the PCM.
Can I Fix the P2087 Code Myself?
While some DIY enthusiasts may be able to diagnose and replace an EGT sensor or repair wiring, it is recommended to consult with a professional mechanic for a proper diagnosis and repair. This ensures that the issue is accurately identified and resolved, preventing further complications down the line.
