OBD2 CODE

P1735 Engine and transmission (P)

We do not have a full sheet for this code yet, with its causes and checks. What you see here comes from the OBD2 code standard.

System: Engine and transmission (P)
Code type: Manufacturer-specific code: its exact meaning depends on the make.

What do I do now?

If the engine light flashes, the car loses a lot of power, overheats or the brakes fail, stop somewhere safe and call for assistance.
If the car drives normally, book a garage and show them this code: its exact meaning and the cause depend on each model.
Tell us what you notice: the diagnosis takes the code, your car and the symptoms into account.

This code does not point to the engine, the brakes or the transmission: you will see the X-ray car with no area marked.
