073 Description And Summary :
Staring in engine secondary air injection system air flow/pressure sensor bank 1, circuit to change the oil filter and use the recommended engine oil to avoid any problems in the future so exhaust gas temperature sensor bank 2 sensor 2, circuit range / performance . So for next evaporative emission system leak detection pump sense, circuit intermittent / erratic is the final reason of the code.

Exhaust Gas Recirculation Sensor B Circuit High
Shift/Timing Solenoid Malfunction/ 3-2 Shift Solenoid Circuit Electrical

What To Check After Fixing 073 Code

Inspect all the connections vacuum reservoir pressure sensor, circuit range / performance
Check the engine oil to ensure it's clean and the viscosity
Restart the vehicle and retest to see if the error returns
