It is not the necessarily the sensor but the relay that controls it. Check the relays it could have been shaken free in the bump. Pushing the relay in and out of its socket could refresh the contact and solve the warning code. To clear the code disconnect the negative battery terminal for a few minutes.

How many miles does it take for a service engine light to reset? I had the light come on and went to my local auto parts store for a free diognostic test, they told me that the upstream O2 sensor was bad....


Nothing to do with miles

If the new sensor was the correct fix, then the light would be off

Maybe the light will go off when the Emissions Monitor Runs,
but doubt it,you went 4 miles & the O2 Data has to be working

You DO NOT Replace parts based on a code
Codes have nothing to do with parts

Codes only indicate an out of range parameter or possible fault

You use the codes to component test the system, that set them
Find a fault or problems
Make the repairs, if necessary

You had no diagnostic test
You had it checked for generic codes only

You have to component test all old & new parts,not
just hang them on there, because of some one is selling
parts with no vehicle knowledge

I have a 2002 Honda EX coupe with about 70k miles. The check engine light came on a few weeks ago. About a week ago, it started to blink periodically. The last time the check engine light came on (about 1...


Check engine light comes on because engine computer has detected a fault. It could be anything, from a cheap sensor to an important component out of specifications, to a service reminder. Most shops (not necessarily Honda dealers, ) have the diagnostic equipment to hook it up to your car and tell you what is wrong, before fixing anything. Usual rates for this diagnostic is below $100, including quote for repair.

Check engine light after every oil change 2005 Honda


This happens because the oil filter needs to be free of air. When the oil pressure sensor drops below a certain value it shuts off the injectors because the PCM. This is a good feature because if you run out of oil for any reason it should stop the engine before damage occurs.

Check Engine light on!!!!!


its the O2 sensor for sure. normally, its good practice to change the sensor when changing out the muffler and cat system. doing it all together will prevent the sensor from faulting.

Check engine light on 1997 Honda accord EX


Hi

If the engine is running without any problems then The fault code which has flagged the checked engine light will either pertain to the upstream O2 sensor, a drop in catalytic efficiency, an EGR issue, or maybe even an EVAP issue.

A lot of EVAP issues can be resolved by simply ensuring that the fuel filler cap is on securely, otherwise a vacuum leak will be detected in the system and the check engine light will come on.

A drop in catalytic efficiency (P0420) is usually temporary and will stay away after a reset.

EGR issues can sometimes be rectified by removing the EGR valve and cleaning it, and the ports on the intake where it was sat, but there are occasions when it has to be renewed.

The O2 sensor issues are a wee bit different. There are a number of fault codes which relate to the O2 sensor, and which make the O2 sensor look faulty, when the O2 sensor is actually attempting to rectify a problem from elsewhere and isn't faulty at all. However, they could also be due to a fault with the O2 sensor. Basically, further checks should be made before condemning the O2 sensor should the fault code relate to the sensor.

Have a code read done and then have the codes reset and see what comes up.

Regards

Geordie
