B0134A/V Sensor Washer Fluid F Control Circuit
- Generic OBD-II code · Body
- How the car detects it
- B0134 is the last of the six A/V sensor washer fluid circuits (B012F for A up to B0134 for F) and covers channel F. The module drives a pump or valve on this channel and reports the code when it finds an open or shorted output. Ford's US10569746B2 lets the computer decide from the measured opacity of a sensor window whether spraying is enough or a wiper must follow. Uber's US10173646B1 runs the cleaning units in an order derived from sensor condition. The KTH thesis for Scania found that changing pump output moved the wave front of fluid across a sensor fascia. Which sensor channel F supplies is not published, and no carmaker documents B0134. Until it is repaired, sensor F loses its washer supply.
- What you may notice
- Sensor F no longer gets washer fluid; only air or a wiper, if present, still works
- Assistance functions that rely on sensor F report reduced availability
- Likely causes
- LikelyWinding of the channel F pump or valve open or shorted
- PossibleWiring of channel F damaged, for example after bodywork near the sensor mount
- RareDriver stage for channel F in the module failed
- Repair
