What is PGM relay?
PGM-Fl Main Relay. Doscription The PGM-Fl main relav actuallv contains two individual rerays. This relay is located at the lett side of the cowl. One relay is energized whenever the ignition is on which supplies the battery voltage to the ECM, power to the fuel injectors, and power for the second relay.
What does IG Opds mean?
IG OPDS (Occupant Position Detection System)
What does the EFI main relay do?
The main relay helps to ensure that the engine computer gets the power that it needs to run and function as intended. The main relay is usually located underneath the hood in the relay box. The high heat that this relay is exposed to can create a lot of damage over time.
What is the HAC fuse?
So the fuse, labeled in the manual as HAC is the fuse for the main blower for Heat and A/C.
How does a main relay work?
These components are basically switches that open and close a circuit by electromechanical or electronic means. The relay works as a conductor in between a low amperage circuit, allowing it to turn a higher amperage circuit on or off.
What does PGM-FI light mean?
The PGM-FI light just indicates the computer detected a problem, a sensor failed to report data or something seems ‘out of bounds’ for the computer (ECU) to process. The PGM-FI light is reset during the start sequence but the stored code is not erased.
What does IG ACG fuse?
The important ACG (S) fuse (#24) protects the ignition switch circuit that supplies battery power to the main relay, which in turn supplies battery power to the fuel pump. You probably only need to worry if the fuse blows every time you insert a new one.
What is the EFI fuse for?
EFI fuse powers your circuit opening relay,fuelpump and sender,O2 sensors, IAC valve,MAF meter, VSV for EGR, VSV for EVAP, VSV for pressure sensor, ECM, and Point side of the EFI relay.
Where is the fuse for SRS light?
The fuse block is on the driver’s side of the engine compartment. Pull out the SRS fuse. In most models, this is fuse #40, located in the lower right corner of the fuse block.
What does LAF heater mean?
The O2 sensor is still used today, virtually unchanged except for the addition of a heater. A special O2 sensor, called a lean air fuel (LAF) sensor, can be used to detect AF ratios in a range from approximately 12:1 to 22:1. The LAF sensors have only been used on the high efficiency Civic models.
What do you need to know about fuse boxes?
Fuse boxes are an obsolete type of electrical panel found in homes built in the 1960s or earlier. If you’ve bought a house with electrical fuses, you need a thorough electrical inspection immediately.
What kind of Fuse does an Edison panel use?
An Edison panel uses Edison fuses that screws in like a light bulb — hence, its name. These protect up to 30 amp circuits. A Type W is general lighting fuse that’s basically obsolete. In other words, while builders moved away from fuse boxes altogether, Type W is almost impossible to find.
Who is the leading manufacturer of fuse boxes?
Federal Pacific Electric (FPE) was the leading manufacturer of these panels until the dangers of aluminum wiring got discovered. The company folded, but millions of American homes still had FPE fuse boxes. If you have an older home and you’re not comfortable with having an FPE fuse box, it’s completely understandable.
Why do I need a 20 amp fuse?
Most importantly, you don’t want a fuse rated for higher amperage on a lower amperage circuit. If a 15-amp circuit uses a 20-amp fuse, the fuse won’t blow when it should so the wiring might overheat and spark a fire. Switching from fuses to circuit breakers gives you the convenience of easily flipping breakers on and off.
