O2 Sensor Basics

This will be the beginning of a series that I'm going to do on computer controlled systems. I've had quite a bit of response to the check engine light video and I think this is the next logical step. I've covered the basic operation of an O2 or oxygen sensor as the basis for closed loop operation. This will probably not be the last time I cover information on O2 sensors, there is soo much more to these than meets the eye.

(2of2) my heck engine light is on> code is:po420 (bad cat?)

thanks for ready and apprieciate all pointers.

[EricTheCarGuy]

@EncinitasLokal That is what the code is for but check the O2 sensor readings to make sure that it's not an O2 sensor problem.

2002>celica gt automatic> 1/10 times example: say i am driving on the freeway and i decide to open the throttle but car doesnt reply.> rpms go up, until i eas off the throttle and press it down slowly, it will pick up and go. i can down shift ;rom 'd' to '2' with no problem, so i doubt im having transmission problems?

[EricTheCarGuy]

@EncinitasLokal Actually that does sound like it might be transmission related if I read you correctly.

@PrinceNeoLloyd If you can't find problem on your own, take it to the repair shop, they find you the problem and you replace the part yourself. This way you save money when not replacing parts by quessing.

is the Oxygen Sensor cleanable? Just like cleaning the Maf Sensor?

Hi there, I have an important question, if you remove the catalytic converter and do this /watch?v=KnYUHwTxKkE&list=FLcH­Bwmz_KHTMGraOeJcRC_A&index=3&f­eature=plpp_video

and the engine light will go off, is this also bad? even if the engine light is off? tnx

[PrinceNeoLloyd]

CAN YOU PLEASE TELL OR SHOW US HOW TO CHECK HEATED O2 SENSORS, IM HAVING A PROBLEM WITH MY S2000 WHENVER MY ENGINE WARMS UP AND ACCELERATE ON THE HIGHWAY MY THROTLLE DOESNT RESPOND ITS LIKE THERE IS NO POWER BUT IF I PRESS IT DOWN SLOWLY IT WILL PICK UP, I REPLACED SPARKPLUGS,IGNITION COIL,MAPSENSOR AND TPS SENSOR,
