B0130 — Av Sensor Washer Fluid B Control Circuit

Generic OBD-II · all makesBody

B0130 indicates a fault in the control circuit for the washer-fluid pump or solenoid that cleans an A/V or ADAS sensor (circuit B). The control module has detected an electrical problem—such as an open, short, or unexpected load—on the circuit that operates the sensor-cleaning washer jet.

Symptoms

What causes it — most likely first

1. Faulty washer pump or solenoid for circuit B

The pump motor or solenoid valve that supplies fluid to the sensor cleaning jet can fail internally—open winding, seized armature, or stuck valve—causing the control circuit to report a malfunction.

2. Wiring or connector fault in the control circuit

An open, short-to-power or ground, chafed harness, water intrusion, or corroded connector pins between the control module and the washer pump/solenoid can set this circuit code.

3. Blown fuse or faulty relay

Loss of power or ground to the washer pump/solenoid from a failed fuse, relay, or shared power distribution point can produce the same circuit-fault indication.

4. Restricted washer fluid supply or clogged jet

A blocked nozzle, kinked hose, or contaminated reservoir can stall or overload the pump, which sometimes triggers a control-circuit fault, though this is less common.

5. Control module output failure

The body or ADAS control module may have a damaged driver for the washer circuit, but this is uncommon and should only be considered after the pump, wiring, and power supply are ruled out.

How it's diagnosed

  1. Confirm B0130 and record any related body/ADAS DTCs and freeze-frame data
  2. Inspect washer fluid level, hoses, and the sensor cleaning nozzle for blockage, leaks, or physical damage
  3. Check the relevant fuse and relay, and verify battery voltage and ground at the washer pump/solenoid connector
  4. Test the pump/solenoid resistance and operation by commanding it on with a scan tool or applying direct power
  5. Inspect the harness and connectors between the control module and the pump for corrosion, pin damage, opens, or shorts; monitor the control output if necessary

Frequently asked

Is it safe to drive with B0130?

Usually yes. The code affects the sensor or camera cleaning circuit, not engine operation. The main concern is reduced cleaning performance for the affected sensor.

Will topping off the washer fluid clear the code?

Probably not if the code reflects a true control-circuit fault. Low fluid can set level-related codes, but B0130 generally points to the pump/solenoid, wiring, or control driver.

Should I replace the engine computer (PCM/ECM) for B0130?

No. B0130 is a body/ADAS washer-fluid control-circuit code, and the engine computer is almost never at fault. A control-module problem is possible but would involve the body/ADAS module and should be diagnosed last.

Can I clear the code after repairs?

Yes. Once the underlying cause is repaired, the code can be cleared with a scan tool. If it returns, further electrical diagnosis is needed.
