2001 Kia Optima

Is this an automatic? P1527, Basically, the tcm is telling the pcm to turn on the lite. You could have tranny problems? Could be issue with transmission range sensor? I saw a service bulletin, kt2007020701, that is a relearn procedure, if the pcm--tcm or transmission has been replaced. I don't know if relearn will help or not?

I just know P0720 and P1529, the P0720 means "Output Speed Sensor Circuit" and the P1529 mean SCAIR Sloenoid Circuit Malfunction.

The Maxivideo MV301 tool 8.5MM is a new release code scanner.

HI there i will try to help .
first code P0741= transmission torque converter is stuck in the off bastion .
1. Check your transmission fluid level to see if low or might need replacing.
2.You might have a Faulty torque converter clutch solenoid valve.
3.If you can check Torque converter clutch solenoid valve harness or connectors
4.If you can check Torque converter solenoid valve circuit to see it is open or shorted.
But first check your trans fluid '''

2 codeP0455=evaporative emission system leak detected .
1. check your fuel cap and mack shore it is on tight before replacing .

3.Code P1529= check T C M it might be do to code P0741.
1.Fix first code P0741and P0455 and clear codes and see if code P1529
comes back.

good luck ziggyone

HI the codes and their respective definitions are below as requested.

P0715 - Input/Turbine Speed Sensor "A" Circuit
P0720 - Output Speed Sensor Circuit
P1529 - Customer Snap Shot Request(Not a essential code or problem)

P1529 indicates that your TCM asked the ECM to turn on the check engine lamp.

The range switch and the output speed sensors are the items that are abnormally affecting the operation of the transmission. The diagnostic logic in your computer can distinguish these issues from one another, so you'll definitely want to do both. You have no diagnostic code for the input speed sensor (P0715) listed, so I have made no recommendation to replace it. In my opinion, it's not a labor-intensive repair, so I wouldn't recommend replacing it unless you have reason to believe it's bad.

DTC - P0720 (OUTPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0720 Output shaft speed sensor system
If the output from the output shaft speed sensor is continuously 50% lower than the vehicle speed for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, it is judged to be an open circuit or short-circuit in the output shaft speed sensor and diagnostic trouble code No. P0720 is output. If diagnostic trouble code No. P0720 is output four times, the transmission is locked into 3rd gear or 2rid gear as a fail-safe measure.
Probable cause
Malfunction of the output shaft speed sensor
Malfunction of the transfer drive gear or driven gear
Malfunction of connector
Malfunction of the TCM

DTC - P0715 (INPUT SHAFT SPEED SENSOR SYSTEM)
Code No. P0715 input shaft speed sensor system
If no output pulse is detected from the input shaft speed sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h (19 mph) or more, it is judged to be an open circuit or short-circuit in the input shaft speed sensor and diagnostic trouble code No. P0715 is output. If diagnostic trouble code P0715 is output four times, the transaxle is locked into 3rd gear or 2nd gear as a fail-safe measure.
Probable cause
Malfunction of the input shaft speed sensor
Malfunction of the underdrive clutch retainer
Malfunction of connector
Malfunction of the TCM

Is needed replace.

First of all, these codes are what are called "Powertrain Trouble Codes' (that's what the "P" means P=Powertrain). TCM Request (Transmission Control Module = TCM). The request was to turn on the 'Check Engine" light.
P0720 - output speed sensor circuit malfunction
P0715 - Input speed sensor (turbin speed) circuit malfunction
P0442 - Evaporative Emission System Leak (Small Leak)
P0455 - Evaporative Emission System Leak (Large Leak)
Check fuel filler cap problems - for Evap Emiss leaks
Replace the pulse generators & have the trans fluid replaced/flushed.
The Main Catalyst System Efficiency Bank 1 Is P0420, not P0442
If you had P0420 code, the catalytic converter is shot... and that's an expensive component.

this should give you some insight

P0715 Input/Turbine Speed Sensor Circuit Malfunction
P0720 Output Speed Sensor Circuit Malfunction

These codes are indicative of bad speed sensors.

When driving the car cold about 10 minutes later the car will kick meduim hard , and the engine light will come on, and then it will be stuck in 3rd gear, but it only does it when the enginge light is on. codes p0720 and p1529 are what I got with the obd2 reader. the P0720 is for the output shaft speed sensor. The sensor was replaced and the computer was reset with the obd2 code reader, but the engine light came back on and I got the same codes,also car kick the same way, What can I do to fix the problem.

All of the codes are related to the transmission. Some indicate the input speed sensor. I'd bring it back to the transmission shop and tell them to deal with it. I don't know what your car was doing before you had the transmission replaced so it's hard to tell whether the repair was needed but since it was done, the problem should be the transmission shops, not yours. Best of luck and please post back, would love to hear how you make out. Greg
