link doesn't work, try again.

 

try now

 

what do you want to know...?

6= engine coolant sensor
23= knock sensor
45... no clue

 

Have you ever checked a sensor for reference voltage or resistance? If you you can put a DMM to the sensor after the car has been running and find the resistance which is representative of the temp. You can find a chart, that shows what temp=what resistance and compare. This will help you determine if the sensor is going bad. You can also check reference voltage to the harness that plugs in to the sensor.
At any time did you try replacing the thermostat?
Rule of thumb- start with the lowest numbered code first (Code 6) usually after eliminating that code the others may go as well (which in this case seems logical).

 

okay, i dont have a way to check which sensor it is. i know that when my engine gets hot, the fan doesnt turn on. i've already replaced that sensor and the fan doesnt turn on still. so what ive done is have a direct link to the fan. maybe this is the reason why code 6 is being thrown. ive checked my knock sensor and it seems to be okay, and yes it's plugged in. but the rpm is still going nuts (it'll jump from 4000 to 4500 rpm when at high milege but when im doing only 30-50 it'll idle normal) dont know what else can be wrong with the knock sensor. as for the 45, im getting backfire from the engine. i know that i must be running fuel too rich but how do i correct that? thanks any input on my three problems would be good!

 

So you've already replaced sensor for the fan? But you can't check the ECT sensor? I'm lost on what you're saying.

 

Code 45 is too rich/too lean fuel mixture. Anyone who messes with a V-AFC, cams/gears or fuel pressure regulator on an OBD2-equipped car gets well-acquainted with that code.

I hate it

Solution? P28 ECU or Hondata.

 

okay, what i mean by replacing the water temp sensor is that i was trying to trouble shoot 3 of the sensors that is involved with the water temp. i replaced the sensor that turns on/off the fan because the fan didnt work (sounded logical). well turns out the fan still didnt work, and i was already drained on $$. so i decided to just connect the fan direct to a switch. anyways, for the knock sensor, turns out that the black plastic piece is broken and the metal inside it broke off from the metal piece that connects to the engine. so if im right, all i have to do is replace the bad knock sensor with a good one and my trouble with the knock sensor would go away right? okay with cel 45, how am i going to correct this. i know that my engine is running too rich, but how do i get it back to normal.
thanks

Do you know what your fuel consumption is? Like as in mpg compared to normal?

 

well not really, because i just did the swap and got the codes thrown at me, so i have no idea on how much gas the thing eats

 

Do you know how many MPG you are getting per tank since the swap? I may be off here in my thoughts, but you could check your fuel pressure and see if its dropping - could have a leaky injector that would cause a rich fuel condition.

 

well i checked the injectors and they look fine, still dont know how i would go about fixing the fich fuel, cause im gettting a lot of backfire when i start the car (w/out pushing on gas) once im driving it, the car doesnt backfire anymore. also, is there a way to get rid of cel 23 other than replacing the ks or getting a chipped p28. by the way, if i was to put in a new ks, would that usaully take care of the problem?
