EXHAUST GAS PRESSURE SENSOR CONSTRUCTION/OPERATION [MZR-CD (RF Turbo)]
id0140f1223200
• Installed to the dash lower panel in the engine compartment together with the exhaust gas pressure correction temperature sensor.
• Converts the exhaust gas pressures before and after passing the diesel particulate filter to voltage signals and outputs them to the PCM.
• A semiconductor type sensor has been adopted with a difference in electrical potential occurring when pressure is applied.
• Output voltage from the exhaust gas pressure sensor increases as the difference in exhaust gas pressures increases.
