DTC P026A-85: Charge Air Cooler Efficiency Below Threshold - Signal above allowable range: Action

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: To validate the repair, clear the DTCs and perform a road test that consists of three drive cycles (engine on/off).

Vehicle Conditions to enable DTC Logging Strategy
- Run vehicle above 40km/h for at least 4 minutes, engine temperature greater than 50 degrees and no other charge air cooler pump faults
Prioritized Checks to Perform
Inspect the cooling system for leaks or damage. Rectify as necessary
- Inspect the coolant pipes for blockages, damage and correct routing. Make sure the coolant is circulating correctly. Rectify as necessary
- Inspect the charge air cooler system for air ingress. Rectify as necessary
- Inspect the charge air cooler for blockages airside and damage. Rectify as necessary
- Inspect the charge air radiator for blockages (External) and damage. Rectify as necessary
- If the fault persists, inspect the charge air cooler pump for blockages, damage or restriction. Rectify as necessary
Top up the coolant system expansion tank. Make sure the level is at maximum when the coolant is cold
Refer to the relevant service information and complete the cooling system filling and bleeding procedure. Check for expelled air during the bleeding process
If P026E-7B was present following the system filling bleeding procedure, clear the DTC and run the charge air cooler pump for 5 minutes. Make sure P026E-7B does not re-set
Allow the system to cool and top up the coolant level to maximum
To validate the repair, clear the DTCs and perform a road test that consists of three drive cycles (engine on/off) If all air has been removed from the circuit (as indicated by coolant visible at all bleed points) and DTC P026E-7B or P026A-85 are present - replace the pump and refill and bleed system
