SOURCE: PCV valve for 2004 Hona CRV

PCV Valve Operation: 0900823d80049deb.jpgA vacuum-controlled metering device that regulates the flow of crankcase fumes in the positive crankcase ventilation system by allowing more flow at high speed than at low speed, and acts as a system shutoff in case of engine backfire to prevent an explosion in the crankcase.
Depending on your engine size, the PCV is a different style and slightly different location.

Usually they are mounted in a hole on your valve cover.... connected by a vacuum tube.
Some are mounted with threads into the engine block (usually by the oil filter)

On the '04 Crv - it is nearly inaccessible behind the AC compressor and beneath what looks like an old vacuum advance. Most PCV valves today do not need to be replaced, unless there is actual valve failure, which I have not seen happen. I would not be concerned about replacing it.

Thanks for using FixYa - a FixYa rating is appreciated!!

SOURCE: Dashboard lights and warning chimes.

The computer detected a fault. You SHOULD NOT drive it around with that blinking, or you will regret it. Take it to the dealership immediately and have them pull the code.

SOURCE: 2004 Honda CRV Check Engine light

the check engine lamp is not affected by things like tyres, brakes etc. It shows that the vehicles engine management system had detected a fault with the engine or engine sensors. Check the engine for broken or disconnected wiring (maybe it was disconnected during the replacing of the hoses but not reconnected). If you fail to locate anything, check the manual for the correct fault code retrieval procedure or take the vehicle to a professional. Tyres may affect your ABS system or Airbag systems but they usually have their own warning lamp and are unrelated to the check engine lamp..

What is the warning symbol on a Honda crv shaped like an engine on the left hand side of the dashboard?


Hello,

The engine shaped light is your Malfunction Indicator Lamp (a.k.a. Check Engine Light). If this is lit, you can take it to any Autozone or Advance Auto Parts, and they will check your codes and tell you what they mean. You can also have them clear it to see if it comes back or not.

I hope this helps.

That means the computer sensed a problem with your vehicle. You need to take it to Autozone and they will read the code for you for free. They will let you know what it is. I would go asap, just in case it is something serious. If you need anything else Kim, please contact me. I am here to help. Thank you so much for choosing FixYa.

LIGHT IN DASH BOARD


DO NOT operate your CRV until you have drained the coolant from the engine and radiator, then flush the system thoroughly w/ water.. Why did you add liquid detergent to the radiator? This will cause foaming of the detergent, and will probably result in diminished cooling of the system. Please describe the dashboard light that's on . Is it some type of symbol? Do you notice anything unusual about how the car is running? Please let me know the answers to the above questions, and the outcome. countrycurt0
