SOURCE: dtc code p0121 and p2135 2007 chevy malibu

both codes refer to the throttle position sensor, the sensor is at the throttle plate, on the side of the throttle body. to test remove the connector to sensor, use a ohms meter to test. put 1 lead to top connection and the other to the bottom one. move throttle and the needles on the ohms meter should move very even, move throttle slow to get a good reading, needle should move without no hesitation, if the test is bad replace tps sensor. if the sensor gets to bad, it can have an effect on transmission shifting. after fixing sensor have the light turned of with an obd2 scanner.

Toyota Highlander code po303 and PO430


The p303 is a misfire on cylinder 3. Most likely a bad ignition coil. The p430 is an evaporate system code. (The system that goes off when your gas cap is loose). On Toyotas, most likely replacing the charcoal canister.

Code po430 comes up twice on scanner little skip and gas milage getting worse


Most likely a failed exhaust converter, that should have lasted
12 to 14 years

Google your codes

So that motor has had issues for years, I would guess

Cylinder Misfires,Rich Fuel Trim ,neglect or something

Have to fix all it's problems, then replace the converters

no year. stated, sigh, nor country, sigh 2.
no DTC posted.!
post the DTC code, do not interpret it , state it. P0xxx?
flat out.
are there other codes? other stored or pending DTC codes?
(errors)
there are many oxy codes, not stating the code is bad news.
each has a different reason, guessing is a fail.

btw , sensor 2 does not run the cars fuel mix. that be sensor 1.
btw, sensor 2, is rear of cat sensors.
this sensors purpose IS TO , warn of a dead CAT.

if the CAT is getting NAILED by rich fuel , the cat can be good
and the code P042x is one, that can be cause by other fueling issues. RICH. if rich (vastly) the cat can overheat. and fail that test. you need to post all facts, in my questions. first.

The first one shows the engine running more that 34 % rich.
check engine compression.
check spark
check fuel pressure.
all 3 are ok, check for leaking injectors or clogged.

Scanner code dtc:26 mixture control continuously rich. How do i fix? 1993 toyota t100 v6


DTC Code 26 Air/fuel ratio RICH

Did you GAP the plugs right? If not, that code will appear on it and a bad O2 sensor will cause it to give off that code also,have someone with a good scanner read and monitor the O2 sensors on it while its running and that will tell you if they are with in range; if not replace the bad ones on it.

Hope helped (remember comment and rated this).

Po420 bank 1 and po430 bank 2 error codes


sounds like O2 sensors to me. I havent changed one on a mustang yet but I havent had any trouble with any others that I have done, they screw in like a spark plug but you will need a special tool, I hope this helps you.

1991 chevy lumina will hardly run


DTC - 22 Throttle position sensor error (signal low), is tps connected?
DTC - 23 Intake air temp sensor error (low temp indicated) check and make sure the sensor is connected
DTC - 43 Knock sensor error, ignore this for now, will not cause rich run.
DTC - 53 System voltage too high, check reference voltage from PCM, it should be around 4.5 Volts, this could be the cause of all your problems, the computer will need to replaced almost for sure.
