Toyota Corolla (E120): On–vehicle inspection

Notice

: ”cold” and ”hot” in these sentences express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).

1. Inspect ignition coil (with igniter) and spark test

  1.  confirm dtc.

    Notice

    : if dtc is indicated, carry out troubleshooting in accordance with the procedure on the following dtc.

  2.  check that the spark occurs.
  1. Remove the ignition coils (with igniter).
  2. Using a 16 mm (0.63 In) plug wrench, remove the spark plugs.
