Measure the resistance of the heater circuit on your new sensor (rear sensor).

Spec is 10-40 ohms.

My guess: Throw away the Bosch sensor. Get a correct DENSO sensor.

That ground strap, along with the one attached to the transmission (mount area?), both need to be in good condition.

They must be able to handle the 100+ amp current load of the starter and the alternator.

I feel pretty good about the car right now, I have replaced a lot of parts on this 01 but theres 1 thing that still bothering me. I bought this car from a so called dealer who was selling it for a friend, he said the timing belt has been replaced, but after having to get a new trans im not so sure. Is there a easy way to check the timming belt without taking too much apart. I know when it does need one it is very expensive.

so called dealer who was selling it for a friend,
You mean a "flipper"? Not a dealership. Not a used car lot.


but after having to get a new trans im not so sure
What does a trans failure have to do with the timing belt?


Is there a easy way to check the timming belt without taking too much apart.
Define "too much".

Even if you open it up to look, you probably can't tell how old it is.
If the timing belt is more than 2 days old, you can't tell how old it is unless it is so old that is has become rotten.

If you CAN open it up yourself, then just slide another one on. Like $25 for a factory belt from a dealer. Inspect the water pump and tensioner while apart.

dealer didn't mention the trans was bad so maybe he lied about the timing belt. I bought it for $2800 inspected put about 80 miles on it and trans went up.It ran fine on the test drive.

Follow the negative battery cable to the body, then to the transmission case.

You really think the "dealer" test drove it any more than you did? I don't.

I bet you just figured out why the previous owner got rid if the car.
There is ALWAYS a reason someone gets rid of their car.
Very few people just get rid of a perfectly good car for no reason.

Resetting the light/clearing memory is not fixing any problem.

Posts 44 and 46 in this thread have the info you need for the P0141 code, or get your own service manual to troubleshoot.
Recheck your wiring and connections too.
You did not get a DENSO sensor?
Was the original sensor made by DENSO or NTK?

P1457 is an EVAP leak code. EVAP control system leakage, canister system or area.
Different problem from the O2 sensors.
Could be a few different things.
Need some understanding of the system and testing.

Ok THANKS I think the one (02 sensor ) that came out was a NTK but if putting a denso one will fix the issue Ill get one.

ALSO the light is actually out now .

I cannot tell you that another sensor will solve the problem, nor can I tell you that it won't solve it either.
I do know why I always want OEM as my first choice though. (The parts catalog does not normally tell who the OEM was for any particular part.)

All I know is the computer did not like what it saw, for some reason.
It's up to you to find out why.

Firing the parts cannon can't fix all problems...no matter how much DangerZone wants you to believe....

Your wrong ezone... Firing the OEM parts cannon WILL eventually fix the problem.. Just might cost 2000 times more than it would diagnosing it properly.

True, but it seems that most people only afford to carpetbomb using the cheapest parts possible....you know, because they are cheap.

The other problem, here anyway. 95% of the time anything even slightly complicated the dealer will diagnose wrong (which I proved a few times already). I'm not knocking you, because you know what's going on. Not all dealer techs do though.
