Except 2.3L/2.5L engine

The resistance between all of these terminals should have been between 0.3–1.0 ohms. If the resistance was more or less than this value, the coil should be replaced with a new one.
Except 2.3L/2.5L engines:
2.3L/2.5L engines (right-hand coil pack):
2.3L/2.5L engines (left-hand coil pack):
If the resistance for all of the readings was between 6,500–11,500 ohms, the ignition coils are OK. If any of the readings was less than 6,500 ohms or more than 11,500 ohms, replace the corresponding coil pack.
NOTE: On 2.3L/2.5L engines, if one coil pack is found to be defective, the other pack does not need to be replaced.
