DTC P0356 Ignition Coil "F" Primary / Secondary Circuit. 1/18/2021 Measuring ignition coil resistance was once a popular test method. Less resistance = more current = stronger magnetic field = more output voltage. The coil depicted in figure 1 could equally well be the primary of an ignition coil. The ohmic resistance of the coil is around 0.2–3.0 Ω on the primary side and around 5–20 kΩ on the secondary side. Coil output is a factor of its turns ratio, primary resistance, and input voltage—assuming it has enough time to fully "recharge" between firing impulses. The 0.2 ohm spec is for the kill switch, not the coil primary resistance. HINT: These DTCs indicate malfunctions relating to the primary circuit. Summit Racing Gift Cards - Always the Perfect Gift! Each ignition coil consists of two separate coils wrapped around each other: the primary winding and the secondary winding. It is expressed in ohms (Ω).
