What does trouble code P0353 mean?
The P0353 code is a generic powertrain code related to the ignition system or an engine misfire. In this case, a malfunction has been found specifically in ignition coil C (or number 3) in the primary or secondary circuit.
What are the codes for the ignition coil?
If your vehicle’s computer detects a problem in the ignition coil circuit, it may send the ignition coil circuit codes P0351-P0358. The last digit of these codes refers to the cylinder where the issue is located. Repair and diagnosis procedures might differ according to the cylinder.
What causes a p0351 code on an ignition coil?
In some cases, the insulation of the coil gets damaged, causing a short. In other cases, the problem stems from bad spark plugs and wiring issues. The P0351 code may appear when your car’s primary computer, which is often referred to as the powertrain control module (PCM), perceives a problem with the cylinder #1 ignition coil or its circuit.
How to check primary circuit resistance on ignition coil?
Attach one lead of your multimeter to each terminal on the coil and set the meter to read ohms. This tests the coil primary circuit; typical readings should be 0.4 to 2 ohms. Consult the manufacturer’s repair information for the exact specifications. Next, check the secondary circuit resistance.
What to do if your ignition coil is not working?
If you don’t detect any frequency signal from the PCM on the ignition coil driver circuit indicating the PCM is grounding/ungrounding the circuit (or there is no visible pattern on the scope if you have one) then leave the coil disconnected and check for DC voltage on the driver circuit at the ignition coil connector.
