B1383 – Oil Level Lamp Circuit Short To Battery

The ODBII code B1383 indicates a short circuit in the oil level lamp circuit, meaning the circuit is receiving constant voltage from the battery instead of functioning normally.

The severity of ODBII code B1383 is moderate.

Common Causes For: B1382 Oil Change Reset Button Circuit Short To Battery

• Shorted wiring or connectors
• Faulty oil level sensor
• Damaged oil level lamp circuit
• Corroded connectors
• Malfunctioning engine control module (ECM)
• Incorrectly installed or damaged oil level sensor
• Grounding issues in the circuit

Common misdiagnosis for B1383 Oil Level Lamp Circuit Short To Battery

• Faulty oil level sensor
• Wiring issues or shorts in the harness
• Malfunctioning engine control module (ECM)
• Incorrect oil level readings due to oil contamination
• Faulty dashboard gauge or indicator light
• Issues with the vehicle’s electrical system
• Problems with the oil pressure switch

Common Troubleshooting Steps

When dealing with an OBD-II code B1383, which indicates an “Oil Level Lamp Circuit Short To Battery,” there are several common troubleshooting steps you can follow to diagnose and potentially resolve the issue. Here’s a structured approach:

• Understand the Code: B1383 typically indicates a problem with the oil level lamp circuit, suggesting that there is a short circuit to the battery voltage.
• Visual Inspection: **Wiring and Connectors: Inspect the wiring harness and connectors related to the oil level sensor and oil level lamp. Look for frayed wires, corrosion, or loose connections.
• **Oil Level Sensor: Check the oil level sensor for any physical damage or signs of wear.
• Check the Oil Level: Ensure that the oil level is within the recommended range. Low oil levels can sometimes trigger warning lights.
• Test the Oil Level Sensor: **Resistance Check: Use a multimeter to measure the resistance of the oil level sensor. Compare the readings to the specifications in the vehicle’s service manual.
• **Functionality Test: If possible, test the sensor by applying a known voltage and checking if it responds correctly.
• Inspect the Circuit: **Continuity Test: Check for continuity in the wiring from the oil level sensor to the instrument cluster. Look for any breaks or shorts in the wiring.
• **Short to Ground: Use a multimeter to check for any shorts to ground in the circuit.
• Check for Short to Battery: **Voltage Test: With the ignition on, measure the voltage at the oil level sensor connector. If it reads battery voltage (12V or more) when it shouldn’t, there may be a short in the wiring.
• **Inspect Ground Connections: Ensure that all ground connections are secure and free of corrosion.
• Scan for Additional Codes: Use an OBD-II scanner to check for any other related trouble codes that may provide additional context for the issue.
• Clear the Code: After performing the checks and repairs, clear the code using an OBD-II scanner and take the vehicle for a test drive to see if the code returns.
• Consult the Service Manual: If the issue persists, refer to the vehicle’s service manual for specific diagnostic procedures related to the oil level lamp circuit.
• Seek Professional Help: If you are unable to resolve the issue after these steps, it may be best to consult a professional mechanic or technician who has experience with your specific vehicle make and model. By following these steps, you should be able to identify and address the cause of the B1383 code effectively.
