B0132A/V Sensor Washer Fluid D Control Circuit

Q: What does code B0132 mean?

A/V Sensor Washer Fluid D Control Circuit. B0132 indicates that the body control module (BCM) has detected a fault in the control circuit for the washer fluid level sensor, designated as sensor D. The BCM monitors the circuit for expected voltage or resistance and sets this code when the signal is out of range, indicating an open, short, or component failure.

AreaAirbags, seats, doors, lights and comfort systems

Symptoms you may notice

Washer fluid low warning light stays illuminated even when the reservoir is full
Washer fluid low warning light never illuminates, even when the reservoir is empty
No other noticeable symptoms besides the warning light
Intermittent warning light that flickers or comes on over bumps
Other body control module functions (like wipers or lights) may be unaffected
Driver information center may display a service message for the washer system

Common causes, most likely first

Faulty washer fluid level sensor D
Damaged or disconnected wiring harness at the sensor connector
Corroded or loose electrical connector pins
Open or short circuit in the control circuit between the BCM and sensor
Failed body control module (BCM) driver circuit
Washer fluid reservoir contaminated or sensor stuck due to debris

How to diagnose and fix it

Verify the washer fluid level is correct and the sensor is properly seated in the reservoir
Inspect the sensor connector and wiring for visible damage, corrosion, or looseness
Disconnect the sensor and check for reference voltage and ground at the harness connector
Test the sensor resistance or signal output with a multimeter and compare to specifications
Check circuit continuity from the sensor connector to the BCM to rule out open or short circuits
If the circuit tests good, substitute a known-good sensor to see if the code clears
If the sensor and wiring are confirmed good, diagnose the BCM or have it reprogrammed/replaced

Don't overlook the washer fluid sensor circuit

A common mistake is replacing the BCM when the actual fault is a chafed wire behind the inner fender liner or a corroded connector pin.
The washer fluid level sensor often shares a ground with other sensors; a bad ground can set multiple codes including B0132.
Aftermarket or incorrect washer fluid can leave a conductive film on the sensor, causing false readings that trigger this code.
Some vehicles use a smart sensor with a small control module; a failed sensor can draw excessive current and damage the BCM driver.
The code may set intermittently only when the washer fluid is low, so testing with a full reservoir can mask the problem.

Can I keep driving with B0132?

This fault does not affect vehicle safety or drivability, so you can continue driving. However, you may not be warned when washer fluid is low, which could reduce visibility in poor conditions, so check the fluid level manually until repaired.
