- How the car detects it
- P22CE is set when the compressor outlet switching valve was told to open but the boost system shows no sign that the switched path changed over. Nissan documents the code as TC Outlet Switching Valve Stuck Closed for the 2016 Titan XD with the Cummins 5.0 litre V8 diesel and its two-stage turbocharger. Bulletin NTB16-051 (May 2016) links it to operation at or below 0 °C and to hesitation on acceleration after an overnight indoor soak followed by a cold drive below -18 °C; the remedy is reprogramming the ECM. The revised NTB16-051a (June 2017) keeps P22CE in the list. Besides software, frozen or collapsed control hoses and a sticking solenoid are plausible causes. The driver notices weak pull while the second stage should come in.
