P0135=O2 Sensor Heater Circuit Malfunction.
I found a guy that explains it well here's the link.
P0135 O2 Sensor Heater Circuit Mulfunction

Here's a link for codes P0446,P0443. https://www.obd-codes.com/p0446 Here's the link for P0403. P0403 Exhaust gas recirculation EGR circuit malfunction Here's code P0135 P0135 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0141 P0141 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0155. P0155 OBD II Trouble Code 02 Sensor Heater Circuit Malfunction Bank 2... Here's the last code.yay P0161. P0161 OBD II Trouble Code HO2S Heater Circuit Malfunction Bank 2 Sensor 2... The last 3 codes might just be one sensor.

You need to have the vehicle put on a dignostic machine , find out what DTC diagnostic trouble code is stored in the computer that controls traction control . Your best bet would be to take to a qualified repair shop , because it sounds like your not up on these thing's

If your check engine light is on and you have a diagnostic trouble code P0135 stored in the PCM's memory... then you've come to the right place to test and troubleshoot the upstream oxygen sensor.
A P0135 DTC says: HO2S Heater Performance Bank 1 Sensor 1... and this means that the PCM (Powertrain Control Module = Fuel Injection Computer) has detected a problem with the front oxygen sensor's heater element or a problem in the heater's circuit (wires).
In this tutorial, I'll show you how to check the oxygen (O2) sensor's heater element and the two circuits that feed it with power (10 to 12 Volts) and ground with a multimeter.
In case you're wondering, where the oxygen (O2) sensor that the code P0135 is accusing of being BAD is... this bad boy is located on the exhaust manifold and before the catalytic converter.
To help you navigate this article, here are its main points:

1. Symptoms of a BAD Oxygen Sensor Heater Element.
2. What Tools Do I Need to Test Code P0135?
3. What Does the Heater Inside the Oxygen Sensor Do?
4. Circuit Descriptions of the Downstream Oxygen Sensor.
5. Start Here.
6. TEST 1: Oxygen Sensor Bank 1 Sensor 1 Test.
7. TEST 2: Checking 12 Volts to O2 Heater.
8. TEST 3: Checking the O2 Heater's Ground Circuit.
9. TEST 4: Ohming the O2 Heater Element.
10. P0135 O2 Sensor Heater Test Summary.

Buying a Digital Multimeter for Automotive Diagnostic Testing (found at: easyautodiagnostics.com).

Scan Tool.

1. Don't have one?... check out my recommendation: Abe's Scan Tool Recommendation.

Wire Piercing Probe.

1. Although this tool is not an absolute must, if you do buy one, you'll realize just how easy it makes testing the voltages inside the wires.
2. If you need to see what this tool looks like, you can see it here:Wire Piercing Probe.

code P0135 is : O2 sensor heater circuit bank 1 sensor 1
yes if sensor tell pcm that air/fuel mixture is lean and the pcm try to make it richer. At max it could stall engine .
but think if there is more to it like spark plug, injectors clean

bad cat converter?

The trouble code P1128 is for a faulty mass air flow sensor or MAP. This is a common problem with 1999-2000 Accents. There is air leakage within the unit and/or the hot wire in the unit is badly contaminated. A bad MAP will cause the vehicle to bog and loose power.
