Compressor not coming on check
If the compressor came on when you were testing it with a test light, it sounds like something is wrong with your ground for your compressor, and completely the circuit through your test light.
I have a 2003 Honda Civic EX. Same problem as many
Hello and welcome to FixYa!
If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow.
The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue.
If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced.
Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat.
A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced.
If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket).
Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!
03 honda civic 1.7L p0401 EGR code.
In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit. Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open Clean out the EGR valve and/or tubing to remove deposits Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model) Replace the DPFE sensor (with a good quality / OEM one)

Civic 06 vti using excesive amount of fuel
The computer will very likely be generating engine fault codes if you have quite excessive consumption and there is no point in guessing what the problem is as there can be numerous causes. You have not mentioned if you have a check engine light showing but if you don't just yet you soon will if the problem persists.
1. Go to a reputable mechanic and have the car scanned for fault codes because it will be very likely throwing some codes if you are having a high engine fuel consumption issue (as opposed to a loss of fuel from the fuel system due to an external fuel leak).
2. On thing you can do yourself is remove the old dusty air filter element in the air intake box ( which no doubt has not been changed since ????) and put in a new OEM air filter unit. A dirty clogged unit will cause your engine to run poorly.
Reset maintenance light
There are 2 way to reset the maintenance light on Civic.
1. Manually reset
To reset this maintenance light, you will put the key in the ignition. Next you will press and hold the odometer reset knob, which can be found on the dash where the car's current mileage is located. While you continue holding that know, you will turn the key to the first position but do not start the engine. After about 10 seconds, the maintenance light should disappear. If the light is still on, you can turn off the vehicle and then try the process again. Once the light is off, you are all set until your next schedule maintenance.
2. Hook up a HDS (Honda Diagnostic System) software on a laptop, the light will go off within minutes.

Fuel filter
Hi. In 1995 Honda began to build their cars with a permanent filter that is part of the fuel sender/pump located in the tank. One less thing to have to worry about.
2003 honda civic o2 how to replace And how do i fin out which once is it
Hi Jesus, Im AL the owner of Big As Auto Repair.
If you have a 4 cylinder engine then you will only have two 02 sensors 1/1 is upstream and 1/2 is downstream. Upstream is the one closet to the engine and downstream is the one farther away from the engine.
If you have a six OR eight cylinder engine you will have four 02 Sensors. 1/1 means Bank One Sensor One. 1/1 and Bank one means right bank and right bank means the side with the number 1 spark plug. SO, 1/1 means, "Right Bank" Upstream 02 sensor. 1/2 means, "Right Bank" Downstream 02 sensor.
2/1 means, "Left Bank" Upstream 02 sensor and 2/2 means, "Left Bank" Downstream 02 sensor. Hope this helps and please visit my auto-repair-website at:
