Hi folks, new to this forum. I have a 92 accord ex coupe, it has a hard time running when I stop or put it in gear. I ran the codes myself and it came up with the following 4 long 3 short blinks, then a 2 to 3 second pause then 6 short blinks and began the same pattern again. Could someone explain to me what I might be seeing. I can be going down the road and it runs fine after 20 minutes the check engine light will pop on . Thanks for your help in advance.

 

i believe that is the code for fuel system or O2 sensor. may want to replace the O2 sensor and reset the error code by pulling the ECU fuse for several seconds. If the error returns, the problem may be in the fuel supply, such as clogged filter.

 

long=10
short=1

4 long & 3 short = code 43 = "fuel supply system"

6 = ECT = engine coolant temperature sensor

The ECT sensor is located in the end of the cylinder-head, sorta below the distributor. It has a 2-wire plug. It's NOT the one located in the radiator-hose-nozzle.
> Look for dirty/corroded/loose wiring connections.

Maybe the code 43 is a result of a bad ECT sensor.

 

Thanks to all who replied on the codes message.

 

I agree with JimBlake, try to diagnose and repair the ECT problem first.
FWIW code 43 is really mis-named. It really means the O2 sensor is reading unburned oxides. AKA running rich.
An ECT problem could cause this condition.

 

Guys what is the best thing to clean this sensor with? thanks

 

You can check for bad wiring connections.

I don't have that Helm book anymore, but there should be a table of resistance (ohms) vs temperature. You can check that at least for room temperature. HondaDude, you got a copy of that ohm-vs-temperature table?

The absolute way to check that sensor is remove it (antifreeze will come squirting out). Stick it in a pot of water along with a thermometer, hook up to multi-meter set for resistance (ohms). Make the water hot & cool to check the sensor against what resistance its supposed to have.
