so I checked out a 2003 xtype jag today, and it was pretty clean
overall, broken ashtray, and loose tail light, and some trim was
missing on the outside. The check engine light was on with 3 codes.
P0037
P0105
P1111
anything serious?

 

P0037: HO2 Sensor heater control circuit low resistance – bank 1, downstream (1/2) - (HO2 Sensor 1/2 heater control circuit-short circuit to ground; HO2 Sensor 1/2 heater failure)

P0105: MAP Sensor circuit malfunction - (MAP Sensor to ECM circuit(s) fault - MAP Sensor failure)

P1111: System (OBD) checks complete since last memory clear

Looks like it needs an O2 sensor and a MAP, or it just might be funky connections.
