Title
P0235, P2263, Replaced Turbocharger Boost Control Solenoid
Complaint
The customer states the check engine light is on.
Cause
Connected a scan tool and found codes: P0235 – Turbocharger/Supercharger Boost Sensor “A” Circuit and P2263 – Turbocharger/Supercharger Boost System Performance. Performed a road test with the scan tool to monitor the live data and found the boost pressure sensor signal parameter was erratic. Visually inspected the turbocharger boost control solenoid wiring harness and found no obvious signs of damage. Used a multi-meter to check for the presence of a short or open in the turbocharger boost control solenoid wiring harness and found there were no shorts or opens present. Used the scan tool to command the turbocharger boost control solenoid on and found the solenoid was inoperative. Used the multi-meter to measure the resistance of the turbocharger boost control solenoid and found the measured resistance was out of specifications. The results of these tests verified the turbocharger boost control solenoid was faulty.
Correction
Replaced the turbocharger boost control solenoid, cleared codes, performed a road test, and verified the vehicle operated properly. The check engine light did not illuminate and no fault codes returned.
