Laymans terms

This code means there's a problem with the car's computer getting too high a signal from one of the sensors it uses to check how the car is working. It's like if you had a thermometer that was reading much hotter than it should be.

Explanation

The Engine Control Module (ECM) monitors the sensor reference voltage circuit. If the voltage is higher than expected, the ECM sets the P06A5 code.

Technical description

The P06A5 code is triggered when the ECM detects a voltage level in the sensor reference voltage circuit 'D' that is higher than the specified range. This can be due to a short to voltage, a faulty sensor, or wiring issues.

Symptoms

• Check Engine Light is on

• Poor engine performance

• Erratic sensor readings

Common Causes

• Short to voltage in the sensor circuit

• Faulty sensor

• Wiring issues or poor connections
