| P0532 A/C Pressure Sensor Circuit Low Voltage |
DTC (PGM-FI)
- Problem verification
-1. Start the engine, and let it idle.
- 2. Turn the blower switch on.
- 3. Turn the A/C switch on.
- 4. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit A/C PRESSURE SENSOR Less than 0.24 V Do the current condition(s) match the threshold?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the A/C pressure sensor and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016 2017 2018 2019 2020) .
- Determine possible failure area (PD SNSR line, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
A/C pressure sensor 3P connector - 3. Turn the vehicle to the ON mode.
- 4. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit A/C PRESSURE SENSOR Less than 0.24 V Do the current condition(s) match the threshold?
YES
Go to step 5.
NO
Go to step 3.
- Determine possible failure area (A/C pressure sensor, others)
-1. Measure the voltage between test points 1 and 2.
Test condition Vehicle ON mode A/C pressure sensor 3P connector: disconnected Test point 1 A/C pressure sensor 3P connector (female terminals) No. 1: Test point 2 A/C pressure sensor 3P connector (female terminals) No. 3: Is there about 5.0 V?
YES
Replace the A/C pressure sensor .
NO
Go to step 4.
- Open wire check (VCC2 line)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS, and wait more than 1 minute.
- 3. Disconnect the following connector.
PCM connector A (51P) - 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/C pressure sensor 3P connector: disconnected PCM connector A (51P): disconnected Test point 1 A/C pressure sensor 3P connector (female terminals) No. 3: Test point 2 PCM connector A (51P) No. 19 - Refer to: PCM Connector for Inputs and Outputs (2017 2018 2019 2020), Is there continuity?
YES
The VCC2 wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM - Refer to: PCM Removal and Installation (2016 2017 2018 2019 2020) , then recheck. If DTC P0532 goes away and the PCM was substituted, replace the original PCM - Refer to: PCM Removal and Installation (2016 2017 2018 2019 2020) or.
NO
Repair an open in the VCC2 wire between the PCM (A19) and the A/C pressure sensor.
- Shorted wire check (PD SNSR line)
-1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS, and wait more than 1 minute.
- 3. Disconnect the following connector.
PCM connector A (51P) - 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode A/C pressure sensor 3P connector: disconnected PCM connector A (51P): disconnected Test point 1 A/C pressure sensor 3P connector (female terminals) No. 2: Test point 2 Body ground Is there continuity?
YES
Repair a short in the PD SNSR wire between the PCM (A47) and the A/C pressure sensor.
NO
The PD SNSR wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting, or substitute a known-good PCM - Refer to: PCM Removal and Installation (2016 2017 2018 2019 2020) , then recheck. If DTC P0532 goes away and the PCM was substituted, replace the original PCM - Refer to: PCM Removal and Installation (2016 2017 2018 2019 2020) .
