What is the severity of this DTC code?

The code P0532 A/C Refrigerant Pressure Sensor A Circuit Low is set when one of the modules monitors a low electrical value within the A/C refrigerant pressure sensor A or it’s circuit. An example of an A/C refrigerant pressure sensor: What is the severity of this DTC?

What does the DTC code p0155 stand for?

Diagnostic trouble code (DTC) P0155 stands for ”O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1).” It is triggered when the vehicle’s computer or the engine control module (ECM) detects an unexpected voltage condition or excessive current draw on the heater circuit of your vehicle’s Bank 2 HO2.

Which is the correct order to diagnose a DTC?

Diagnose any current DTCs in the following order: 1. DTCs that begin with a U 2. Any of the following: B1000, B1001, B1008, B1015, B1016, B1019, C0550, C0551, C0561, C0563, C0565, P0601, P0602, P0603, P0604, P0606, P0607, P060D, P062F, P2105, P2107, or P2610 3.

What does the code p0532 a / C pressure sensor a circuit low mean?

Most times, you can diagnose this type of code without opening the refrigerant system. The code P0532 A/C Refrigerant Pressure Sensor A Circuit Low is set when one of the modules monitors a low electrical value within the A/C refrigerant pressure sensor A or it’s circuit.
