P2752 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2752 can be described as Intermediate Shaft Speed Sensor C Circuit Intermittent. The error code P2752 would start triggering when the PCM would detect some faults in intermediate shaft speed sensor C circuit signal. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P2752 trouble code would indicate that an intermediate shaft speed sensor C circuit signal which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination of the malfunction indicator light.

What causes this problem with the Intermediate Shaft Speed Sensor C Circuit Intermittent?

• There can be inoperative intermediate shaft speed sensor
• Some electrical problems in the wires between the speed sensor and modules used
• There can be distorted ECM and/or TCM
• Defective input shaft speed sensor
• Broken output shaft sensor
• Some issues related to the shift solenoid
• Stained or less automatic transmission fluid (ATF)

1. Speed Sensor - Do you know the symptoms of bad speed sensor? If there would be a failure in the speed sensor, then you might notice harsh or improper shifting, cruise control might not work and at the same time the check engine light would start flashing. You can always rely on us as we have the best auto parts for our customers.
2. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
3. Transmission Fluid Pump - The first indication of any transmission related problem will the illumination Check Engine Light. Other major symptoms indicating bad transmission fluid pump can be bad shifts, delayed response and fuel burning smell coming from under the hood. Thus, immediate replacement is advisable.
4. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
5. Automatic Transmission Module - A defective transmission module will affect the gear shift mechanism and also affected during acceleration and deceleration. This will lead to affected engine performance and fuel delivery system. Thus, replace faulty transmission module now!
6. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
7. Diagnostic Tools - Take the help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P2752 code by mentioning some major symptoms below:

Common Symptoms

• Illumination in the numerous instrument panel light
• There might be hard shifting
• The driveability might be unsatisfactory
• Variable engine speed

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2752:

• It is essential to restore the flawed engine drivability sensor
• Recondition the non-functioning input speed sensor
• The malfunctioning PCM should be repaired or replaced as per the need
• The shift solenoid should be restored to working order
• Make sure to mend the faulty intermediate shaft speed sensor C
• It is necessary to perform proper service of the unsound output speed sensor
• Adjust the flawed transmission fluid

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of ecm, transmission control module, shaft speed sensor, pcm, automatic transmission fluid, digital volt, ohmmeter, pcm, automatic transmission module and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

The initial step is to inspect the level of the transmission fluid. The fluid should be very clean and at the same time should be filled adequately. After that you should carefully locate the intermediate shaft speed sensor. Many a times these sensors are mounted directly to the transmission housing. One can also access the sensor from under the car hood. If you want to gain access, then you can always remove other constituents like the air cleaner and box, miscellaneous brackets, wires etc. Just make sure that the sensor as well as connectors should be in perfect working condition as well as fully connected. TIP: If the automatic transmission fluid is burnt as well as smelling, then it is a sign that there is a requirement of new fluid. Then you must do a full transmission service with all new filter, gasket and fluid.

Remove and clean the accessible speed sensor. It would not cost much and if you find out that the sensor's pickup is very grubby after it has been removed, then you would be able to wash all these problems. A clean sensor pickup can be ensured by using a brake cleaner and a rag. The readings of the sensor can be altered by dirt and shavings, so you must make sure that yours is neat and tidy! NOTE: If there are any signs of rubbing on the pickup, then it would indicate inadequate spacing between the reluctor ring as well as the pickup. Most likely there might be some faults in the sensor and is now hitting the ring. If a replacement sensor still doesn't clear the ring, then you must refer to manufacture procedures for adjusting the pickup/reluctor gap.

Carefully inspect the sensor and its circuit. The sensor can be inspected by utilizing the multimeter and particular manufacturer specifications and different electrical values should be measured between the sensors pins. These tests should be done from the same wires but at the corresponding ECM or TCM connector pins. This will check the integrity of the harness involved as well as the sensor.

Common Mistakes When Diagnosing The P2752 Code

• There can be a failure in the powertrain control module
• Defaults in the intermediate shaft speed sensor
• Some issues related to the wiring
• Transmission control module failure
