DTC P2228 - Barometric Pressure Sensor Circuit Low🔗
Conditions for Setting DTC P2228🔗
- Engine Running
- Barometric Pressure Sensor ≤ 0.1 volts
- The above must be present for a period of 128 instances/cycles or greater to trigger DTC P2228
Diagnostic Steps🔗
| Step | Action | Value(s) | YES | NO |
|---|---|---|---|---|
| 1 | - Key on, Engine running - Within VCM Live, open the Baro sensor DTC Minimum voltage parameter, does the Baro sensor parameter display 0.1 volts or less? |
≤ 0.1 volts | Go to Step 2 | Intermittent Issue - Refer to Intermittent Diagnostics |
| 2 | - Key off - Disconnect the CORE connector "C" - Check continuity between the Baro sensor connector signal cavity 3 and ECU baro signal connector "C" pin 29 - Do you have continuity between them? |
Go to Step 3 | Repair the circuit as necessary, locate any wires that need to be repaired or replaced | |
| 3 | - Check for continuity between the baro sensor connector 5 volt reference cavity 2 and ECU splice SP6 - Do you have continuity? |
Go to Step 4 | Repair the circuit as necessary, locate any wires that need to be repaired or replaced | |
| 4 | - Check for continuity between the baro sensor connector low reference cavity 1 and ECU splice SP3 - Do you have continuity? |
Go to Step 5 | Repair the circuit as necessary, locate any wires that need to be repaired or replaced | |
| 5 | - Replace the baro sensor - Is the replacement complete? |
Go to Step 6 | N/A | |
| 6 | - Clear any DTC from the ECU - Turn the ignition off and wait 30 seconds - Start the engine and operate the engine to full operating temperature - Observe the Check Engine Light on the Menu bar in VCM Live - After operating the engine within the test parameters, check for any store codes - Does the engine operate without any stored DTCs? |
