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.
