Question about Honda CR-V

Open Question

I have a check engine light on. It started when after each fill up the light would go on when the tank got to half full. If I set the tank cap back again the light would go out next time I started up. This has been doing for awhile. Recently I had to jump start the car (seatbelt in door) when battery was dead. Since then the light has been on all the eime and the key in the ignition warning tone does not work. I had a diagnostic done - and 2 codes came up P0134 and P1298. The estimate was nearly $800 for replacing the oxygen sensor and eletri load detector. Yet when I go online the parrts cost for Bosch replacements are under $300. Do both need replacement and can I do them myself or how much mechanics time to replace them if I buy the parts online? 2003 CRV

Check all fuses, then check the wiring of the two 02 sensors on either side of the cat. converter. If the fuses and wiring are fine, it is likely one of the oxygen sensors; one is about $50 and the other is $200 (parts only). Use only Honda recommended parts, not BOSCH.

SOURCE: 2002 Civic trouble code P1298

Usually this code comes up when an O2 sensor has failed.
to be safe, replace both (one before and one after cat)
The only thing that is hurting right now is your gas mileage.
However, if you are running rich - extra gas is making its way into the cat, and your element will run out prematurely.
Best to get it corrected now to avoid further (costlier) repairs down the road.
Each o2 sensor is approx $50.
If you can only afford one - do the front one first.

It sounds like you have either a lean or rich condition ocurring,could be exuast leak,vac leak,leaking fuel preasure regulator,cat convertor.At this point would go to dealer for diagnosis.

Honestly it is not very expensive to replace, but it is not extremely important. What it does is measure the oxygen/fuel level coming out of the engine. This tells the computer that the engine is either using the right air/fuel mixture or allows the computer to change the mixture slightly to allow the car to run properly. You could pull the sensor out and clean the terminal as it usually has alot of carbon build up due to its location, but this is normally a temporary fix. I hope this helps you with your problem.

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.

Why is the coolant overflowing when the temp guage gets half way?


well the tank must never be full, when engine is cold
was it? (read operators guide to see methods)
water expands hot, and the tank captures this expansion
that is normal.
what does "until its all gone", mean, what is IT?
there are lots of tests.
the first one, is,
IS the engine overheating,?
try a new rad cap, they are dirt cheap.
and, is the oil or carbon in the RAD neck, cap off , cold engine>?
is there water in the engine oil, milky dip stick end?
same with A/T trans? milk, or pink/red ATF.
is there steam going out the tip of the exhaust pipe on a fully hot engine>? yes/no?
is air and water exploding in to the side expansion tank.?

cold engine
remove rad cap'
fill rad with 50% AF.
new cap back on.
put 50% AF 1/2 way up in to expansion tank(its marked clearly)
start engine , does it overflow now>?

When I fill the tank VSC and engine lites come on for a while. Also when the tank gets below half full they come on


When you put fuel in the car try not to over fillit. It needs a little air in the tank to ptoperly perform. Thats why the light comes on. You Should be fine

The amber engine light on my Honda Civic Si 2004 (93,000 kms) comes on when my gas tank is at the half tank mark, then two lines below half tank it goes off, and then just above the empty line it comes...


The gas tank has a sensor to monitor fuel evaporation. If it determines that fuel is evaporating from the tank, the check engine light will come on. It usually is caused by the gas cap losing it's seal. Get a new gas cap,make sure it is made for your car. That should eliminate the light.

My check engine light came on shortly after filling my gas tank. I did put more gas in the tank after the gas pump clicked that it was full. what could be the problem


If your check engine light came on shortly during or after filling the tank, and then goes off later, thats quite a relief. It really happens, and lucky for you dont have to bring your vehicle to a shop if the light persisted. Here are some tips regarding this issue: turn off the ignition switch before opening the fuel tank cap. Turn on and start only after the caps are properly closed. The scenario is that, whenever we refill gasoline on the tank, the pressure and the vacuum inside the tank are being upset, sometimes creating some kind of signal glitch which may be misinterpreted by the engine control module, and thus shortly illuminate the check engine light. I hope this lightened you up. Have a safe trip. : )

Check engine light indicator is on...after total


Obviously you have something above the tank that's leaking. That will result in a code the same as a bad or loose gas cap. At this point, the only way you can find the source is to take a good look at everything, even if it means dropping the tank to do that. (better than wasting fuel or having a fire start under there).

How do i put coolant in a polo 1.4 year 2000


open radiator and fill the radiator. open expasion tank and fill it to the FULL mark.
start the engine with the radiator cap off. keep topping the radiator up as the air comes through the system and the level goes down. keep it FULL. top up the expansion tank if necessary back to the full mark, do not fill it to the top you will only get coolant all over your engine bay!
gently rev the engine for 20 seconds just to send the water round and get some air out of the system. top up both radiator and tank again if required. refit the radiator cap and expansion tank cap. go for short drive. check the levels again (be careful with the radiator cap since the coolant will be hot now!) - should be settled now.

ready for the road!

The engine runs fine until it get to half a tank of gas.


I wonder if it could be that the tank's not getting vented properly... have you tried just taking the gas cap off and replacing it, without adding fuel? is there a suction sound when you take the cap off?
