The P0C87: Hybrid Battery Temperature Sensor ‘G’/’H’ Correlation refers to a mismatch in temperature readings between Hybrid Battery Temperature Sensors ‘G’ and ‘H’. This issue could stem from faulty sensors, wiring problems, or circuit issues affecting the accuracy of the readings.
P0C87 – Quick Overview
| Code | Information |
|---|---|
| Meaning | P0C87: Hybrid Battery Temperature Sensor ‘G’/’H’ Correlation |
| Is it serious? | Yes, a mismatch in sensor readings can cause improper battery management, affecting the performance and safety of the hybrid battery system. |
| Possible causes | – Mismatch between sensor readings – Faulty temperature sensors – Wiring or circuit issues |
| How to diagnose? | – Check the correlation between sensors ‘G’ and ‘H’ – Test both sensors – Inspect wiring and connections |
P0C87 Meaning
The P0C87: Hybrid Battery Temperature Sensor ‘G’/’H’ Correlation code indicates a discrepancy between the temperature readings from Sensors ‘G’ and ‘H’ in the hybrid battery system. This mismatch could be due to one or both sensors malfunctioning, wiring or circuit issues, or communication errors between the sensors and the control module.
Step-by-step diagnostic guide
| Action | Description | Tools Needed |
|---|---|---|
| Check for Other Codes | Use an OBD-II scanner to check for any additional codes related to sensor or circuit malfunctions. This may provide more context. | OBD-II Scanner |
| Check Sensor Correlation | Use a diagnostic tool to compare the readings from Hybrid Battery Temperature Sensors ‘G’ and ‘H’. Ensure the values are consistent and match manufacturer specifications. | Diagnostic Tool, Multimeter |
| Test the Temperature Sensors | Test both temperature sensors independently to ensure each is providing accurate readings. Replace any faulty sensors. | Multimeter, Temperature Sensor Tester |
| Inspect the Sensor Circuit | Visually inspect the circuits for both sensors for any signs of damage, disconnections, or corrosion that could cause reading discrepancies. | Flashlight, Multimeter |
| Check Wiring and Connections | Inspect the wiring and connections between both sensors and the control module for loose or damaged connections. Repair as necessary. | Flashlight, Multimeter |
| Test Circuit Continuity | Perform a continuity test on the circuits for both sensors to ensure no breaks or resistive connections are causing the mismatch. | Multimeter |
| Clear the Code and Test Drive | After repairs, clear the P0C87 code using an OBD-II scanner and take the vehicle for a test drive to verify that the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
| Recheck for Codes | After the test drive, re-scan the vehicle to ensure the P0C87 code has not returned. | OBD-II Scanner |
