If you have replaced the speed sensor then i would think the problem lies in the wring as you seem to think also, you could try to fault find the problem or just change the wiring harness , both i would imagine are a laborious task , i would start removing the harness , paying close attention where each connector goes and as removing harness check for any damage etc you may find the problem wire/connector before you get harness completely out ,if no visable fault carry on with the new replacement. This code is triggered when NO signal is received by the ECU/PCM , so a close inspection of the speed sensor wiring and mounting would be the first step , good luck

I have a 1998 dodge caravan 3.3L fault codes p0500 p0700 p0720 p0715, how do I repair and replace sensors to pass smog test


Follow the links for each fault code.
http://www.obd-codes.com/p0500
P0700 Transmission Control System Malfunction
P0720 Output Speed Sensor Circuit Malfunction
P0715 sets when there is an error in the transmission's input speed sensor signal. On the front of the trans there is an input and output speed sensor that the trans controller looks at for shifting control.

While the code could have set because of a wiring or connection problem, it's almost surely the sensor. Input speed sensor failures are not uncommon.

The input speed sensor is mounted right on the front of the trans directly under where the cooler lines attach. It threads directly in and has a 1" hex for a socket for removal. If the wiring and connection look visibly ok then I would recommend replacing the sensor

Engine code p0011


This DTC code is a result of a mechanical fault of the VCT unit or related components, so there is no need for electrical diagnosis.

Refer to vehicle specific repair manual to perform component tests for the VCT unit.

Notes: Dealer techs have advanced tools and the ability to follow detailed troubleshooting steps, including the ability to test components using a scan tool.

P0715 Turbine speed sensor circuit A. Sets after clearing, data shows no glitches in signal and reads steady rpm value at idle and when off idle. No other codes. Circuit test seems waste of time seeing...


You may have a slipping torque converter clutch or worn bands. Contact a local transmission repair shop for further diagnoisis. The turbine speed sensors measure in and out speed of the main shaft, if a excess differance is seen then it will turn on the light and set the appropriate fault codes.

Service code PO715


Hi there:
P0715 Input/Turbine Speed Sensor Malfunction OBD Fault Code.

Make sure the TSS sensor connector is good. Since you replaced the engine it is possible the wires/pins in the connector are loose or bad. I have seen where the wires break inside the insulation at the connector.You could have a bad TSS sensor(200-400 ohms good), if you have a multi meter we can check the circuits too. I would check the connector and then clear the code , test drive and see if it comes back. The PCM uses this sensor to control shift patterns so a fault is stored in the PCM. P0715 is for a loss of TSS signal during operation.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

I am getting both PO715 and PO751 error codes on my 2000 grand caravan. Does this mean the tranmission needs to be rebuilt?


P0751 Shift Solenoid A Performance or Stuck Off (generic OBD description)
P0715 Input/Turbine Speed Sensor Circuit Malfunction

The service manual does not list P0751 as a valid code for your vehicle. You may want to re-check it to make sure you are reading it correctly. Also note that many generic OBD code readers cannot give complete renderings of "manufacturer-specific" codes. You may be getting this code if you are using a generic OBD code reader because there is a manufacturer-specific code present and P0751 is the closest "generic" rendering of the code that the code reader could find.

P0715 is a CIRCUIT malfunction. NO, this does not mean that your transmission needs to be overhauled. This means that either the turbine speed sensor has an electrical failure in itself or the circuits between the turbine speed sensor and the computer are defective. Electrical diagnosis needs to be done.

Please note that BOTH of these codes can be cause by low battery voltage and attempts to diagnose the circuits involved should only be done AFTER verifying that the battery and charging system is working properly.

Santa Fe Code p1529


I am sorry the above codes is general error code , the error your getting is car specific hence the codes where not there in the list:

P0715
Input speed sensor system

If no output pulse is detected from the input shaft speed (PG-A) sensor 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 or short circuit . In the input shaft speed sensor and diagnosis code P0715 is output. If diagnosis code P0715 is output four times, the transmission is locked into 3rd gear (D range) or 2nd gear as a fail-safe measure

P1529
TCM MIL request signal, this code sets in the computer engine control module when there is a transmission fault code
