Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
When attempting to diagnose an intermittent problem, use scan tool to review malfunction history information. This data can be used to duplicate a problem.
A malfunctioning 2/3 coil, 2/3 ignition wire or 2/3 spark plug will not cause DTC P0352 and/or P1352 to set. A blown EIS fuse will cause a no-start condition but an IC 2/3 DTC may not set. An IC 2/3 circuit fault may set a cam missing DTC P0340. If engine starts with a fault on the IC circuit, a misfire DTC P0300 may also be set. If there is an open in the IC 1/4 circuit a misfire on those cylinders will occur.
