Engine Running
Lambda Bank 2 Sensor 1 Sensor ≥ 4.9 volts
The above must be present for a period of 128 instances/cycles or greater to trigger DTC P0152

Step

Action

Value (s)

YES

NO

1

- Key on, engine running

- Within VCM Live, open the Lambda sensor DTC parameter, does the lambda sensor parameter display a voltage of 4.9 volts or higher?

≥ 4.9 volts

Go to Step 2

Intermittent Issue

(Refer to Intermittent Diagnostics)

2

- Key OFF

- Disconnect the Lambda 2 sensor connector and check for continuity between cavity 1 & the ECU connector "C" pin 15

- Do you have continuity?

 

Go to Step 3

Repair the circuit as necessary, locate any wires that need to be repaired or replaced

3

- Key OFF

- Disconnect the Lambda 2 sensor connector and check for continuity between cavity 2 & the ECU connector "C" pin 16

- Do you have continuity?

 

Go to Step 4

Repair the circuit as necessary, locate any wires that need to be repaired or replaced

4

- Key OFF

- Disconnect the Lambda 2 sensor connector and check for continuity between cavity 4 & the ECU 12v C15-4

- Do you have continuity?

 

Go to Step 5

Repair the circuit as necessary, locate any wires that need to be repaired or replaced

5

- Key OFF

- Disconnect the Lambda 2 sensor connector and check for continuity between cavity 5 & the ECU connector "C" pin 22

- Do you have continuity?

 

Go to Step 6

Repair the circuit as necessary, locate any wires that need to be repaired or replaced

6

- Key OFF

- Disconnect the Lambda 2 sensor connector and check for continuity between cavity 6 & the ECU connector "C" pin 21

- Do you have continuity?

 

Go to Step 7

Repair the circuit as necessary, locate any wires that need to be repaired or replaced

7

- Replace Lambda 2 sensor

- Is the replacement complete?

 

Go to Step 8

N/A

8

- 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 DTC's?

 

System is now operational and ready to be tuned
