DTC P0236-24: Turbocharger/Supercharger Boost Sensor "A" Circuit Range/Performance - Signal stuck high: Action
WARNING: This page is about a different variant/trim than selected.
- Vehicle Conditions to enable DTC
Logging Strategy
- Ignition must be off for greater than 5 seconds to enable the start up check on the next ignition on, the sensor is then compared to ambient pressure every time engine speed is less than 1200 rpm and throttle blade position is less than 7% for 5 seconds
- Prioritized Checks to Perform
- Check powertrain control module for related ambient pressure Diagnostic Trouble Code(s) and refer to relevant DTC index, rectify these first
- Be aware of what the actual expected atmospheric pressure is in your location and compare to the manifold sensor for an additional cross check. Check the boost pressure sensor, manifold sensor and ambient pressure sensor values at ignition on only, All sensors should read atmospheric pressure. If the boost sensor is reading higher than the ambient and manifold pressure sensor, check the electrical connections for correct installation
- Using the Jaguar Land Rover approved diagnostic equipment check datalogger signal
- Boost Pressure Control (0xF470)
- Inspect TMAP post WCAC sensor connectors for signs of water ingress, and pins for damage and/or corrosion
- Refer to the electrical circuit diagrams and check TMAP post WCAC sensor circuit for short circuit to ground, short circuit to power, open circuit, high resistance
- Install new TMAP post WCAC sensor, only when diagnosed as failed
