| Main Action |
- Monitor sensor response - slow response
|
- Poor connection
- Faulty HO2S
- Faulty ECM
|
| Prerequisite Condition |
- Upstream O2 sensor operative readiness is detected with sensor tip temperature over 640°C (1184°F)
- O2 sensor forced stimulation is active
- P013300 diagnosis is synchronized with P042000 monitoring.
|
| Threshold Value |
- Integral value (Lambda signal amplitude measured divided by Lambda signal amplitude of a slow sensor) is greater than 1.

| Diagnostic Time |
- 20 Fuel Trim Controller Cycles
