Engine fault warning light (check engine) in the E-Tech Híbrido engine: causes

In the E-Tech Híbrido engine, 1 documented fault may be the cause: stalling and injection warnings on the 1.2 E-Tech 200 (HR12).[1]

What to do now

Garage soon

If it stays on steadily, you can drive gently to a garage and ask for a fault code read-out. If it flashes or you notice a loss of power, slow down and get to a garage as soon as possible.

What it means

The orange engine-shaped warning light comes on when the ECU detects a fault affecting combustion or emissions. If it flashes, it usually points to misfires that can damage the catalytic converter.

Engine faults that cause it

From most to least important. Under each fault, how the symptom shows up. Check the affected years and versions on each page.

  1. Source for the symptom[1]

Other common causes: engine warning light

Besides the documented faults of the E-Tech Híbrido, these are the most common causes on any car according to the sources.

  • Faulty lambda sensor (oxygen sensor)[3][4]Common
  • Dirty or blocked EGR valve[3][5]Common
  • Deteriorated or blocked catalytic converter[3][6][7]Common
  • Spark plugs, coils or ignition leads in poor condition[3][8]Common
  • Faulty injectors[3]Possible
  • Blocked particulate filter[5]Possible

What to check first

  1. Note how the light behaves (steady or flashing; yellow, orange or red) and whether the car loses power, jerks, makes noises or gives off smoke. That decides whether you can carry on or must stop.[3][9]
  2. Check that the fuel filler cap is properly closed: a badly closed cap is one of the causes RACE cites and the easiest to rule out.[3]
  3. Have the codes read through the OBD port at a garage with a diagnostic machine: the error codes point to the part that is failing (sensor, EGR, injectors, ignition, catalytic converter).[3][7][8]
  4. Repair the cause and only then reset the light with the diagnostic machine. If you clear it without repairing, it will come back on.[3]
