• Q: How to replace Ignition Coil No.1 on 2005 Toyota Prius?

  A: The replacement of Ignition Coil No.1 begins with removal of Rear Floor Board No.2 then continues with Deck Floor Box Rear removal and ends with Rear Floor Board No.3 removal. Begin by disconnecting Engine Wire No.3 at Battery Negative Terminal then proceed to remove Ignition Coil No.1 by detaching Engine Room Relay Block No. 2 with 2 bolts and disconnecting 4 ignition coil connectors and taking out the 4 bolts securing 4 ignition coils that each use 1 bolt for attachment. The installation sequence requires you to position the 4 ignition coils using 4 bolts which have an 9.0 Nm (92 kgf.cm, 82 in.lbf) torque while reconnecting the 4 ignition coil connectors, then install Engine Room Relay Block No. 2 with 2 bolts at 8.4 Nm (86 kgf.cm, 74 in.lbf) torque. After reconnecting Engine Wire No.3 to the Battery Negative Terminal you can replace Rear Floor Board No.3 along with Deck Floor Box Rear and Rear Floor Board No.2. The power window control system requires initialization as the final step.
