What is fault code p1646 on Jaguar XKR?
P1646 is a faulty heater circuit on bank 1 upstream o2 sensor. If you have the V6 2.5 petrol engine, then bank 1 is the exhaust manifold nearest the bulkhead ( firewall if you in the states). Replace the upstream o2 sensor. Cost around £70from dealer…not available elsewhere.
Where is Bank 1 sensor 1 Jaguar X type club?
I have the Engine light on and the readout from the scanner is P1646. I understand that this relates to Bank 1 sensor 1, again I believe that this is the upstream sensor on the firewall side and is located in the exhaust manifold.
What is the sensor code on a Jaguar?
The P1646 on mine does not mention which one it just says its the sensor control module. The original code I have was P0037 which says its a sensor but that has now gone since changing both of them but they might be not the correct ones so now I have the P1646.

What causes the p0446 code to come back?
P0446 tends to be returned by diagnostic testing when the control circuit for the evap vent valve is not achieving the seal that enables the EVAP system in the vehicle to hold pressure. The evap vent valve in most makes and models depends on a supply of a 12V battery voltage with key on.
What is the code for the EVAP vent?
The evap vent valve in most makes and models depends on a supply of a 12V battery voltage with key on. The ECM driver closes this valve when grounded and will set code P0446 if there is an open or short to ground or battery voltage or it is not possible to form a vacuum seal.
