My car have the code p1111 and p1646,which is that?


p1111 is nothing just letting you know system is ready after codes had been previously cleared, p1646 is 02 Sensor Control Malfuntion Bank 1 Upstream. Possible causes for p1646 o2 sensor went bad,short circuit to ground, short circuit to voltage, or open circuit. Code p1646 bank 1 sensor 1 o2 sensor control malfunction. Bank 1 is the rear bank and sensor 1 is the upstream sensor which you can see if you look between the engine inlet manifold and the brake booster(LHD). It is screwed into the manifold and has the grey connector next to the booster. You can check power to the heater on the white with green stripe wire. Any other testing will require a scan tool with datalogging capabilities. There were some VINs around your year that had their wires for that sensor twisted up by a faulty tool in the factory but you should be able to see that sort of damage easily.

Check engine fault code 1646


P1646 is a defective heater circuit on an o2 sensor. (bank 1 sensor1)I'm assuming you have the 2.5 V6 petrol engine? Replace the upstream sensor on bank1 to cure problem.

Engine management light on Fault code found p1646 what does it mean ?


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.

X type fault codes p1111 & p1646 can you shed any light on them for me please ?


P1111 - System Pass
This is flagged after DTCs have been cleared, all engine management OBD diagnostic monitor drive cycles HAVE BEEN COMPLETED.

P1646 - Linear O2 Sensor Control Chip (Bank 1)
Its listed as either a faulty heated HO2 sensor ie lambda sensor (upstream bank 1) or a short (presuming the ECM is OK as no other codes)
Did you replace the right one... bank 1 is at the back of the V6, bank 2 is at the front so its the back one.

Hope this helps (remember to rate tis answer).
