B0130 code meaning
A/V Sensor Washer Fluid B Control Circuit
What B0130 means
B0130 reports a fault where the module switches A/V sensor washer fluid B, the second of six channels running from B012F (A) to B0134 (F). A/V almost certainly stands for autonomous vehicle. Uber's cleaning layout (US20180015907A1) shows what such a channel switches: a compressor charges an air accumulator, one reservoir with a level sensor holds the fluid, and several pumps feed the cleaning heads, each started separately by the vehicle computer. Kautex sells its Allegro system for cameras and lidar on vehicles from level 1 to level 5, mixing water and air jets. Which sensor channel B serves is not published, and no carmaker documents B0130. With the circuit open or shorted, the sensor on channel B is no longer washed.
B0130 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.3 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B0130
- The camera or lidar on channel B stays dirty while the others are cleaned
- Driver assistance or automated driving reports a blocked sensor or is withdrawn
Common causes of B0130
- Most likelyPump motor or valve coil on fluid channel B open or shorted
- PossibleCorroded or loose connector at the pump, exposed to washer spray and road salt
- Less likelyOutput stage for channel B in the controlling module failed
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0130 means
| B | Body system: airbags, seat belts, power seats, lights and climate control. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 30 | The exact fault in that area. |
What to do next
- Note B0130 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about B0130
What does B0130 mean?
B0130 means "A/V Sensor Washer Fluid B Control Circuit". B0130 reports a fault where the module switches A/V sensor washer fluid B, the second of six channels running from B012F (A) to B0134 (F). It is a generic code, so it means the same on every make.
Is it safe to drive with B0130?
B0130 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B0130 fail an emissions test?
B0130 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is B0130 to fix?
Difficulty: medium. A typical repair takes 0.3 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will B0130 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
