How to Diagnose and Solve B1480 Wiper Washer Fluid Level Sensor Circuit Open Issues

Introduction

If you’re experiencing issues with your wiper washer fluid level sensor circuit, you may see a B1480 error code on your dashboard. This can be frustrating, but don’t worry – with a little bit of knowledge and some DIY skills, you can diagnose and solve the problem yourself. In this article, we’ll walk you through the steps to diagnose and solve B1480 wiper washer fluid level sensor circuit open issues.

What is the Wiper Washer Fluid Level Sensor Circuit?

The wiper washer fluid level sensor circuit is responsible for monitoring the level of washer fluid in your vehicle. When the fluid level is low, the sensor sends a signal to the dashboard to alert the driver. If there is an issue with the circuit, the sensor may not be able to send the signal, resulting in the B1480 error code.

Diagnosing the Issue

To diagnose the issue, you’ll need a multimeter and a wiring diagram for your vehicle. Here are the steps to follow:

Step 1: Check the Fuse

The first thing to check is the fuse for the wiper washer fluid level sensor circuit. Use your vehicle’s manual to locate the fuse box and find the fuse for the circuit. Use your multimeter to check if the fuse is blown. If it is, replace it and see if the error code disappears.

Step 2: Check the Wiring

If the fuse is not the issue, the next step is to check the wiring for the circuit. Use your wiring diagram to locate the wires for the circuit and check for any breaks or damage. Use your multimeter to check for continuity in the wires. If there is a break or damage, repair or replace the wiring.

Step 3: Check the Sensor

If the wiring is not the issue, the next step is to check the sensor itself. Use your multimeter to check the resistance of the sensor. If the resistance is not within the manufacturer’s specifications, replace the sensor.

Solving the Issue

Once you’ve diagnosed the issue, it’s time to solve it. Here are the steps to follow:

Step 1: Replace the Fuse

If the fuse was the issue, replace it and see if the error code disappears.

Step 2: Repair or Replace the Wiring

If the wiring was the issue, repair or replace the damaged wiring.

Step 3: Replace the Sensor

If the sensor was the issue, replace it with a new one.
