Documented by: CHEVROLET (USA), FORD, JAGUAR, MAZDA, TOYOTA — the meaning can differ between manufacturers

I got fault code C1287. What does it mean?

C1287 does not mean the same thing on every car — manufacturers reuse the number for different faults. 5 makes document it: Chevrolet (USA), Ford, Jaguar, Mazda, Toyota. Find your make below.

What does C1287 mean on a Chevrolet (USA)?

C1287 on Chevrolet (USA)

On Chevrolet (USA) vehicles C1287 is documented as: Steering sensor rate malfunction. C1287 is stored when the ECU sees malfunction on steering. That describes how the circuit is behaving, not which part has failed — the wiring, the connector and the component itself can all produce it, which is why the checks below start with the cheapest.

Usually one of: Wiring or connector fault in the circuit; Component failed electrically; Supply or ground problem feeding the circuit; Controlling module fault, though this is the least common of the four.

Check first, cheapest first:

  1. Read all stored codes — a general fault code is often the symptom of a more specific one
  2. Inspect the connector and wiring for the named component
  3. Check supply and ground at the component
  4. Measure the component against specification
  5. Replace the component once wiring and supply are ruled out

How do I know which one applies to my car?

Which one is yours

A generic OBD reader gives you the number, not which of these meanings your manufacturer assigned to it. To get to the specific one:

  1. Use a brand-specific scanner — VCDS for VAG, INPA or ISTA for BMW, XENTRY for Mercedes, Forscan for Ford. It shows the manufacturer's own text rather than the generic one.
  2. Read all stored codes together — the neighbouring ones usually point at which system is involved and narrow the list.
  3. Check freeze-frame data: the RPM, temperature and load at the moment it triggered indicate which system was active.
  4. If you have no brand scanner, tell me the make and model below and I will tell you which of these applies to your car.
What kind of code is C1xxx?

Code family

C1xxx is suspension, steering, active systems.

How serious is it?

Severity

Suspension or steering — on active systems (ESP, air suspension) the code usually comes from a sensor, not the part itself.

And on my car specifically?

That is what holds for C1287 in general. From here it depends on your engine — tell me which car it is and what it does, and I will give you the steps for it: real procedures, torque figures and diagrams instead of general advice.

Who makes these pages, and how

TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.

The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.

The same code can mean different things on different makes. Match the meaning to your make before acting on it.
