This code can be set for either a short to ground, short to power, high resistance or open circuit on Oxygen Sensor for bank 2, (HO2S21). Bank 2 is on your right when standing at the front of the engine facing the crank, and this sensor is the first in line; before the converters. Check out our circuit testing article at for help with testing. From what I can tell the wires from that sensor are RED/WHT, WHT/RED, GRN, BRN. I would recommend checking related wiring for opens, shorts or chaffing before condemning the sensor. Just for info you may want to check out our article on Oxygen Sensors at Hope this helps.

What is P1111 AND P1647 on jaguar x-type

Hello! Code P1111 is pointing at a defective air temperature sensor.

Jaguar does not have a code P1647. However if the code was in the P164x area it is an effect not a cause; The air temp. sensor controls fuel flow by sensing a differential in temperature; This device is called a MAP. A small black component with two mounting bolt holes with an electrical connector. It cost around $80 if purchased at an auto parts store. Follow back from your air filter towards the intake (need to remove plastic engine cover) to locate the MAP.

If you need any additional information Please include it when you rate this solution.

Trouble code p1647

hi, i work as a mechanic and have just had this code (p1647)on an 02 2.5 ltr x type. got the definition for 02 banks as well. as there are 2 sensors on each bank i took a look at the live data and it showed a slugish response on sensor two(after the cat). unplugging the sensor in the front cat brought up another code for bank two sensor two so this is obviously the right sensor. changed sensor and sent the car out, hope this helps, jon.
