SOURCE: I have a 2001 hyundai elantra.my check engine

Satlaan: You need an odb2 scanner to extract the trouble codes. If you don't have one you can buy one for around $30 from most auto part stores. Alternatively, some auto part stores (Auto Zone for example) will read your trouble codes for you, for free. The trouble codes could be anything from a loose gas cap to a misfire, without the scanner there is no way to know.

Rashidas: How did you fix the speed sensor? This is not the speedometer cable that bolts to the transmission, but a separate sensor inside the right side front wheel behind the brakes.

This AllExperts.com post explains it pretty well.

Don't just assume it is the sensor though,, that wiring gets beat up by all the **** you drive over, so look at the wiring carfully.

Hope that helps,
Ellie

SOURCE: My car's check engine codes are p1723, p0740,

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

SOURCE: vehicle wont change up into gear reverse gear not

P0734 - 4th gear incorrect ratio. P1529 Malfunction Indicator Lamp Request. Problem is in the transmission.
Take/Tow your vehicle to an authorized Hyundai dealership and pay the diagnostic fee... they will tell you exactly what the problem is and the cost of parts/labor to fix it... at least this way you'll know what the problem is and what's required to fix it.

Transmission is acting up,went to autozone and it shows 2 codes p1529 and p720 please explain ? thanks Ralph


P0720 almost always points to a problem with the output speed sensor itself. The sensor is located on the top of the transmission near the rear. It's held in place with one 10mm bolt. You may be able to access with a long extension and a 10mm swivel-socket. If not, you'll need to remove the air box. You'll find the sensor semi-hiding under the wiring harness that runs across the rear portion of the top of the transmission.

P1529 is simply an indicator that the transmission control module (TCM) requested the engine control module (ECM) to turn on the check engine lamp.
Let me know if this helps or if you need mor help.

Check engine light with following codes p 1529 p0720 p0715


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.

Code 1529


Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. P1529 is a TCM MIL request to the
ECM.
TCM = Transmission Control Module. The sluggishness is really what is known as 'fail safe' mode (3rd gear). You should have had other codes besides P1529 to identify which system in the transmission caused the problem.

Having the same problem the other guy described.


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.

P1529 and P0720 does not seem to be understood.

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

P0118 means Engine Coolant Temperature Circuit High Input.

02 kia optima code p1529


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.

Obd codes 720 1529 3600


P3600 in my listings shows as being reserved by the SAE for future code definitions, and that there is no current definition for a fail code as such. P0720 is a transmission output circuit failure. Sounds like something in the transmission controls has gone south, creating the P1529 code that emissionwiz correctly identified. However, "output circuit" is kind of vague. Are there any driving impressions you can share? Does the car seem different in any way?
