Set Condition
WARNING: This page is about a different car, the 2025 Jeep Grand Cherokee. However, it is still accessible from the selected car via links, so may be relevant.
- Condition one: Map and ELCM Pressure Sensor difference of 2 kPa for 60.0 seconds.
- Condition two will fail if any of the following are true:
- The PCM detects low flow during the first 0.20" Reference Orifice check.
- The PCM detects high flow during the first 0.20" Reference Orifice check.
- The PCM determines that the ELCM Pressure Sensor signal is not between the minimum and maximum calibrated thresholds, based on BARO (see chart below) , during the first 0.20" Reference Orifice check.
- The PCM determines that the ELCM Pressure Sensor signal is not between the minimum and maximum calibrated thresholds, based on BARO (see chart below) , during the second 0.20" Reference Orifice check.
- The difference between the two reference checks is more than 0.5 kPa.
- The difference between the two BARO reference checks is more than 1.0 kPa.
