Had a bad sensor and replaced it, still haveing trouble
I have a 2001 Chevy Monte Carlo, my check engine came on and I took it to autozone to have it scaned, it said bank 1 senor 1 so I replaced it and had the codes reset, well the light came back on and the codes saying the same thing. Is it Possiable the I have a bad fuel pump? And the car is hard to start both cold and warm.

Re: Had a bad sensor and replaced it, still haveing...
Yes it could be the fuel pump and you might try to change the fuel filter first. cheeper and easy to change compared to a fuel pump.pull the battery cable off pos. side for 20 seconds and replace it, the codes will be cleared and if it comes on again, the code will be what is going on now, hope this helps, thanks robert b.

How hot does the engine get in degrees F? Even if the radiator fan is new, does it turn on? Any applicable trouble codes? Is your coolant boiling over? Maybe your getting combustion gases in your coolant?
Hi, check the connection on your temperature sensor. If the connection is good, replace the sensor. The cost is about $11 at autozone. The sensor is located at the back of the engine, near the transmission. See pictures below. Use some water pump sealant on the threads when installing the new sensor. Please let me know if you have any questions, and thanks for using FixYa.
Hello. I understand your frustrations as I too own a 2001 monte carlo and have had the same problem...along with several others. My engine temp gauge would show ZERO degrees because of the bad coolant temp sensor. So I replaced it with one from autozone (BIG MISTAKE) The one from autozone was **** and gave the car a different problem. The fans would not run while the engine was running and would run when the engine was off until the battery rundown protector would shut them down. this lasted about 2 weeks during which I had to keep my heater on (in the middle of summer) to keep my car from over heating because my fans wouldnt run. The autozone jerks said "if my temp gauge was working then the sensor was doing its job" and that "there is another problem" Well I finally called the dealership and they told me that autozone is junk and to try advance auto parts and to get the next one up from the cheapest...this is what they use...and NASCAR uses. It was a few dollars more (around $25) Problem solved. However a few months later the cooling fans went completly out..this was due to them experiencing such high temperatures for 2 weeks. I replaced them with ones from a salvage yard for $50. Dont let this happen to you...
sounds like a fuel management problem. the catalytic converter is getting to hot due to tryin to burn off the excess fuel not burned. causing the muffler to overheat get it scaned at autozone for free. sounds like a o2 sensor runnin lean dumpin more fuel. or a bad mass airflow sensor good luck
