p0336 is faolt code for crankshaft position sensor fault check the wiring to the sensor and check the reluctor

I would need to know what year model this is, engine capacity and engine code to confirm but generally on the x-trails that fault code refers to a mechanical fault on the fuel pressure regulator. This is for the YD22DDTi engine.

This code is for the electronic throttle valve is see a slow return rate on throttle plate or a open circuit and ECM has entered a fail safe operation mode. Test throttle plate motor for open circuits or shorted to ground.

try this see if it helps!! http://g35driver.com/forums/engine.../225448-engine-code-p1121.html

this code relates to fuel mixture to air so first check for any leaks worn pipe's check air filter also worth adding a fuel addative to clean through the valve,cylinder and catalytic converter and then get the code re read.Did you get the code removed when first had it read if not do the above and get the code cleared then drive again and recheck as sometimes a stored code can remain even when fault has been cured

code p1121 refers to throttle position motor---malfunction===causes--throttle position motor
--- fix--replace the unit.
