FAQs

Where is the ECU fuse on a 2007 Honda Civic? ›

To locate the Civic's main electrical plug look under the hood in the engine compartment electrical plug box. It should be on the driver's side of the bay next to the firewall. The Backup Memory/ECU fuse should be clearly labeled on the flip side of the box' plastic cover.

Located under the dashboard. Fuse locations are shown on the label under the steering column. Locate the fuse in question by the fuse number and label number.

In the under-dash fuse box you can find the PGM-FI-mainrelay 1& 2 and also the ETCS control relay.

If You want to know where the starter relay is located on Your 2012 Honda Civic, look no further. The starter relay is located under the hood in the engine area. Its specific location is on the driver's side of the motor right next to the battery.

The power distribution center, or fuse block, located under the hood houses most or all of the vehicle's fuses and relays. It contains a relay for the ECM that is powered up when the ignition key is turned to the on position. This ECM power relay acts as a switch that supplies power to the ECM.

ECM stands for Engine Control Module, and ECU is short for Engine Control Unit. These two acronyms represent the same component and are used interchangeably.

In your model the flasher/turn signal relay is built into the MICU which is a computer board that is part of the fuse box under the drivers side of the dash.

Your fuse box will have two sets of fuses. At the bottom will be 15-amp and 20-amp screw-in fuses with glass faces that are exposed and visible. These fuses will service branch light circuits and outlet circuits. At the top will be 30-amp or 40-amp cartridge main fuses for ovens, laundry rooms, or stoves.

Usually, you will find two fuse boxes in the car. One is located under the hood and the other is found in the dashboard or near the steering wheel.

What is a PGM-FI relay? ›

This relay controls power to the ECU, and the fuel pump. Without power to the rest of the fuel-injection system, or fuel pump, you won't be going anywhere!

Programmed Fuel Injection, or PGMFI/PGM-FI, is the name given by Honda to a proprietary digital electronic multi-point injection system for internal combustion engines. It has been available since the early 1980s. This system has been used in motorcycles, automobiles, and outboard motors.

Most often, a true starter relay is a small black cube plugged into an electrical fuse/relay box in the engine compartment, whereas a starter solenoid is (in most cases) attached directly to the starter on the engine (although it is sometimes located elsewhere in the engine compartment).

One of the first and most common symptoms is simply no response from the starter when you turn the key – no noises or engine cranking at all. Sometimes, repeatedly trying the ignition can produce a result, but that's not guaranteed. It usually means there's a faulty connection in the solenoid.

How to locate your 10-11th gen Honda Civic, Accord or TLX Ecu Part Number. You can visually inspect your ecu's part number on the ecu located on the drivers side of the engine bay near your intake.

Well, you see, that fuse protects the ECU (Engine control unit or ECM engine control module) from over amperage's. So if there's an electrical surge, the brain is protected. On a newer model car the ECU/ECM controls everything ignition related AT LEAST. Timing, ignition, air.

The easiest way to perform an ECU reset is by removing the fuse from the fuse box. It is a very simple process, and all you have to do is pull out the car key, remove the fuse from the fuse box, and then put it back after about 15 to 20 seconds. Doing this clears any long-term memory stored in the car's ECU.
