Table of contents

|P0353 SCION code possible causes

  • Faulty Ignition Coil 3
  • Ignition Coil 3 harness is open or shorted
  • Ignition Coil 3 circuit poor electrical connection
  • Faulty Engine Control Module (ECM)

|How do I fix the P0353 SCION code?

Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.

|Cost of diagnosing the P0353 SCION code

Labor: 1.0

The cost of diagnosing the P0353 SCION code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

|When is the P0353 SCION code detected?

Each ignition circuit is continuously monitored by the Engine Control Module (ECM). The test fails when the ECM does not receive a valid pulse signal from the ignition coil.

|What are P0353 SCION code possible symptoms?

  • Engine Light ON (or Service Engine Soon Warning Light)
  • Lack/Loss of Power
  • Engine may be harder to start
  • Engine hesitation
  • Rough engine idle

|P0353 SCION code description

A Direct Ignition System (DIS) is used on this vehicle. The DIS is a 1-cylinder ignition system in which each cylinder is ignited by 1 ignition coil, and 1 spark plug is connected to the end of each secondary wiring. A powerful voltage, generated in the secondary wiring, is applied directly to each spark plug. The sparks of the spark plugs pass from the center electrodes to the ground electrodes. The ECM determines the ignition timing and transmits the ignition (IGT) signals to each cylinder. Using the IGT signal, the ECM turns the power transistor inside the igniter on and off. The power transistor, in turn, switches on and off the current to the primary coil. When the current to the primary coil is cut off, a powerful voltage is generated in the secondary coil. This voltage is applied to the spark plugs, causing them to spark inside the cylinders. As the ECM cuts the current to the primary coil, the igniter sends back an ignition confirmation(IGF) signal to the ECM, for each cylinder ignition.
