Sensors not ready 2001 Chevy S10. I have driven more than 500 miles and sensors still read not ready. 02 Sens Not Ready, 02 Sens Htr Not Ready, Catalyst Not Ready.

Wow, did you hook it up to a scanner and get any codes? If you can post what the codes are, it would be simpler to digagnos

What was the original trouble code?

What they probably said was the car needs to be driven to allow the computer to reset the sensor readings.
If the battery is disconnected or the computer looses memory, the car has to be driven to allow the sensors to function and the system to complete a full test. The drive normally consists of various speeds, highway and city, and it has to get up to normal temp. 50-100 miles is recommended.
The OBD test looks for any sensors or readings that are out of normal range.

The O2 heater is part of the O2 sensor itself. You would need to replace the oxygen sensor if the heater is an issue.

As a rule it takes about 50 miles for the computer to finish it's readiness tests. Some take longer so I would drive it about 75 miles and then check.

HAVE GARAGE CODE SCAN VECHICLE.IF YOU ARE GETTING CATALYTIC CONVERTER FAULTS OR OXYGEN SENSOR FAULT CODE.YOU HAVE FAILED SENSORS OR VACUUM LEAKS. SOMETHING IS UPSETTING THE EMISSION CONTROL SYSTEMS.

sounds like the IAC (idle air control valve) or possibly a vaccum leak. As far as the cat. converter not ready, the vehicle must be driven a certain distance or go through a certain amount of drive cycles for all the systems to be monitered. Most of the time i just take the vehicle for a 50 mile drive on the freeway and that usually does it.

you will need to drive approx 500 miles it will eliminate the not ready but will bring back the codes

the computer needs to be reset by performing a code erase then drive 500 miles

Drive the car for 2 miles non-stop and take it to smog inspection WITH OUT TURNING OFF THE CAR!! the key is that the car goes threw the test while the engine is running ...

if the car is turned off ... u will have to repeat procedure ...
