B0192 code meaning
Front Wiper Speed Performance
What B0192 means
B0192 is publicly unverifiable: it appears neither in a J2012 list nor in any carmaker's documents. A performance fault, unlike the circuit fault B0220, means the wiring may be fine while the wipers sweep too slowly or irregularly. Speed is usually judged from the park contact, which closes once per revolution. US5216340A uses exactly this on cars with two wiper motors: from the timing and the back-EMF voltage seen at each park contact it detects that one motor runs faster and briefly holds it back until both are in step again. US5694011A shows the extreme case, a motor so loaded by frozen or stuck blades that the park signal stops. Bosch now also offers brushless and reversing drives whose electronics set speed and end positions themselves. Typical result: smeared, slow or out-of-step wiping.
B0192 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2 hours
- Clears after repairWhen cleared with a scanner
Symptoms of B0192
- Wipers sweep noticeably slower than usual, especially on high speed
- Wiper arms judder, hesitate or run out of step with each other
Common causes of B0192
- Most likelyWiper linkage pivots dry, corroded or binding, slowing the motor
- PossibleWorn motor brushes or commutator, reduced torque and speed
- Less likelyBlades frozen to the glass or heavily loaded by snow
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of B0192 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). |
| 92 | The exact fault in that area. |
What to do next
- Note B0192 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 B0192
What does B0192 mean?
B0192 means "Front Wiper Speed Performance". B0192 is publicly unverifiable: it appears neither in a J2012 list nor in any carmaker's documents. It is a generic code, so it means the same on every make.
Is it safe to drive with B0192?
B0192 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will B0192 fail an emissions test?
B0192 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 B0192 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will B0192 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
