P0A18 - OBD Trouble Code

<<See All OBD Codes

Worried? See the error code P0A18 constantly flashing on the screens? Don’t know what to do? Where to start from? Well, we are here at your service. Only for our customers we have listed jotted down all the information regarding the error code P0A18. For your information, this OBD-II code high voltage system may not operate is generally referred to as a motor torque sensor circuit range/performance. Also, it should be noted that the engine computer (PCM) constantly performs the duty of regulating the amount of power the hybrid transaxle (motor/transmission assembly) generates. The code P0A18 is stored by the powertrain control module when if the PCM does not receive any signal. One can observe the motor torque sensor built internally in the hybrid transaxle assembly.

It should be noted that the error code P0A18 is triggered on vehicles that are equipped with an electronically controlled automatic transmissions. Also, the 3-4 shift solenoid holds the responsibility for actuating the hydraulic circuits to activate clutches or bands that further alter the gears inside the automatic transmission.

What causes this problem with Motor Torque Sensor Circuit?

• An unsound motor torque sensor
• Loose or shorted motor torque sensor harness
• A fragile electrical connection running in the motor torque sensor circuit

1. Powertrain Control Module - Diagnosed a malfunctioning powertrain control module? Well, a faulty one can give rise to a lot of problems. So, we advise you to repair or replace a faulty one immediately in order to overcome the complications caused by the error code P0A18.
2. Motor Torque Sensor - Hate these halts as much as we do? Well, no more stopping! Change or mend your defective motor torque sensor in order to avoid the problems caused by the error code P0A18. Tune into Parts Avatar for good quality motor torque sensor.
3. Motor Torque Sensor Harness - Having problems with the motor torque sensor harness? Don’t you worry, Parts Avatar has it all. A distorted motor torque sensor harness could end up being the root cause behind the error code P0A18.
4. Engine Control Unit - Get your error code solved by replacing or repairing a damaged engine control unit. Get yours changed immediately.
5. Electronic Control Unit - A distorted electronic control unit can be harmful triggering the error code P0A18. We advise you to change it as soon as possible.

As a matter of the fact, the P0172 code sharing similarities with other codes like P0A17 and P0A18 can often make the task of detection of the P0172 a strenuous task. Here are the common symptoms that can help the driver detect easily.

Common Symptoms

• An engine light blinking on and off (or service engine soon warning light)
• Most of the times the high voltage system may fail to function at all
• Failed operations of the vehicle

Know thee code but don’t know how to start with the process of correction? Want to correct the trouble code P0A18? All that we want you to do is to read the information we have written down for you:

• To begin with, it is important to fix a malfunctioning motor torque sensor immediately
• It is advised to visually inspect the components in the system. Any harness located in the motor torque that is burnt or open should be replaced or repaired as soon as possible.
• Measures should be taken instantly to mend a powerless electrical connection running in the motor torque sensor circuit

It is essential to diagnose this fault code. Here are some steps which a technician should follow for diagnosing the problem that triggered a P0A4F code to be stored:

The technicians should make use of a device called an OBD-II scanner. This scanner should be connected to the onboard computer inside of the vehicle. It will then retrieve data from the vehicle to determine what issues might be present in the vehicle. The technician will likely first clear the code and then retest the vehicle. If there is an issue, the code will reappear. From that moment, the technician can start to narrow down the actual cause and determine what needs to be done to repair the vehicle.

Common Mistakes When Diagnosing the P0A18 Code

Performed all the repairs but still see the code P0A18 displaying? Well, it could be appearing due to mistake while performing the repairs. So, only for you we have listed here a few common mistakes that should be avoided while the procedure is being performed:

• A malfunction in the hybrid transaxle assembly
• Powertrain control module (PCM) failing to function at all
• Wiring issues
