Guide To P2853 OBD Error Code Solutions

 <<See All OBD Codes

The trouble code P2853 can be elucidated as Clutch "A" Pressure Discharge Performance. The transmission should detach when it is coming to an end. Now if the transmission would fail to disengage correctly, then the P2853 fault code would start appearing.

The signals which come from the switches and sensors control the clutch pressure control solenoid. The clutch pressure is adjusted to be suitable to the engine load state and vehicle driving state. Then it would become possible to finely control the clutch hydraulic pressure with high precision and there would be the attainment of the smoother shift change characteristic

What causes this problem with the Clutch "A" Pressure Discharge Performance?

• There can be inoperative control valve assembly
• There might be low brake solenoid valve

1. Engine Control Module - Most of the time it is difficult to intercept the ECM faults and thus must be checked for thoroughly. There can be a problem with the circuit or the software might have malfunctioned. Thus repair, replace or reprogram the component as per requirement.
2. Powertrain Control Module - If the PCM is faulty, it can store wrong OBD codes and can lead to misdiagnosis. This can happen due to misinterpretation of data received from the various sensors and components which also affects the vehicle’s performance. Thus, replace it immediately.
3. Car Battery - The car battery can also be at fault and might have the problem of overcharging and fast discharging. This can cause increased temperatures and can also affect the functioning of various sensors like the speed sensor, temperature sensor and many more. Thus, replace faulty car battery today!
4. Transmission Fluid Pump Harness - Damaged transmission fluid pump harness can cause problematic transmission performance and can lead to transmission slipping, rough shifts, fuel leakages and delayed engagements. Buy new harness now!
5. Manual Transmission Shifter - If your manual transmission shifter is broken, then you will be able to move the shifter into any position, but keep in mind that the car transmission would stay in the exact same gear. Get it checked and replace if needed.
6. Electronic Control Unit - If the ECU is at fault, it will not be able to read the boost converter temperatures correctly leading to underperformance. Thus, replace faulty ECU now!
7. Diagnostic Tool - Choose from our diagnostic tools collection that will come in handy to detect and correct the OBD error code.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• The service engine soon light can start lighting up
• Transmission might not shift correctly

The repairs which you will have to do to correct this fault code are simply straightforward; you can surely pinpoint the necessary repairs on the basis of your diagnosis. Have a look at some common fixes:

• The malfunctioning control valve assembly should be repaired or replaced as per the need
• Carefully adjust the faults in the engine control module
• The clutch should be restored to working order

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 car clutch, brake solenoid, control valve assembly, transmission clutch, transmission switch, transmission sensors, clutch pressure control solenoid, auto transmission 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 mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the solenoid itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P2853 code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every component of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the clutch "A" pressure as well.
• If there are some faults in the clutch "A" pressure, then it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P2853 Code

• There can be some faults in the internal transmission
• There might be less transmission fluid level
• Wiring problems
