Question: I have a 2002 jaguar s type, 4.0 L with the codes 705 and 125 coming up…what does this mean?

Answer:

P0125 – Insufficient Coolant Temperature for Closed Loop Fuel Control
P0705 – Transmission Range Sensor Circuit Malfunction (PRNDL Input)

These codes are generic OBDII codes from the following site…

I would guess from the first code your coolant sensor is shot, or the
wiring is bad to the sensor.  The second one related to the
transmission shifter location, which the sensor may be in the
transmission or the console where the shifter is.  I don’t have a
Jaguar manual handy to tell you specifics.  Alldata repair manuals are
an excellent source for this kind of specific info.
