Guide To P0AF6 OBD Error Code Solutions

<<See All OBD Codes

The trouble code P0AF6 can be defined as Drive Motor Inverter Temperature Sensor 'B' Circuit Intermittent/Erratic. The error code P0AF6 would start triggering when the PCM would detect some fault in motor temperature sensor. 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.

The motor temperature sensor “B” detects the temperature of the transaxle fluid. The resistance of the thermistor installed in the motor temperature sensor “B” varies with the changes in the transaxle fluid temperature. The construction in the motor temperature sensor “B” and how it is connected to the HV control ECU are the same as those of the motor temperature sensor “A”.

When a failure is detected in the Drive Motor Temperature Sensor circuit, the engine control module (PCM) will set code P0AF6.

What causes this problem with the P0AF6 Drive Motor Inverter Temperature Sensor 'B' Circuit Intermittent/Erratic?

• Malfunctioning drive temperature sensor
• Motor temperature sensor harness might be unlocked
• Motor temperature sensor circuit might have bad electrical connection

1. Diesel Particulate Filter - The diesel particulate filter acts as an important component in managing the particulate emissions in the exhaust system. If the filter is damaged, it may lead to increased emissions and pollutants through the tailpipe. Thus, replace damaged filter now!
2. Engine Control Module - It is not always the components, but the ECM that can also be faulty. It can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
3. Exhaust System Parts - Your exhaust system begins at the engine with the purpose of removing toxic gases and fumes from your vehicle. The components are a series of pipes, catalytic converters, sensors, mufflers, and often a resonator, as well as other emission devices. Thus, replace damaged exhaust system now!
4. Powertrain Control Module - Powertrain Control Module can also be faulty in rare cases and thus needs through checks for system and software errors. Thus, check and replace it, if required.
5. Electronic Control Unit - The ECU manages the cooling system to control the battery operating temperatures and thus must be replaced if found faulty. Thus, buy new ECU modules and components from us!
6. Diagnostic Tool - Make use of quality diagnostic tools to resolve any OBD error code. Buy quality diagnostic tools from us!

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0AF6 code to be stored:

• Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
• The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
• The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
• The tests related to the hybrid battery and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further be helping the cause.
• The P0AF6 error is triggered if there is a physical problem with the battery which could cause the engine performance to go off.
