Good Afternoon,

After several weeks, the work on my 2003 xtype 2.5 is done. We replace all O2 sensors, upper and lower intake manifold gaskets, new spark plugs, Power Brake Booster vacuum Hose, Fuel Pressure Sensor, Throttle body gasket, O-Rings and MAP sensor. She's all back together, and started right up, no hesitations, just purring away. After about 40 miles, the engine light went out. We plugged in the scanner, and all the codes are gone except for P1000 System Readiness Test Not Complete. I've driven her 170 miles so far in two days, and the code is still there. How long does it take to clear this code?

Many Thanks,

Mic

 

You must complete the correct drive cycles to get the monitors to ready status, or DTC P1111.

Have a read of this thread about resetting the X400 monitors:
