Xkr p1647 fault code

You need to get your vehicle to a good mechanic as this could be almost anything! One of the cylinders isn't firing correctly. This could be a fuel, an air or a spark issue. It will need further investigation. It also suggests there might be a problem with one of the O2 sensors on the exhaust system. I was unable to find a listing for P1317.
P0306 = Cylinder 6 - misfire detected.
P1000 = OBD Systems Readiness Test Not Complete.
P1314 = Misfire Rate Catalyst Damage Fault - Bank 2.
P1316 = Misfire Rate Exceeds Emissions.
P1317 = (no code found).
P1647 = Linear O2 Sensor Control Chip (Bank 2).

i think p1647 is a generic code that is not a problem code but a system check code put in each time the ignition is switched on and will always be present if you have no eml/other function light on then no worries hope this helps

O2 sensor upstream

the p1647 is not a dodge code please check again by turning the key to the on position and off three times the third time your odometer will show you the codes

P1647 ECM HO2 Sensor control
malfunction -
Mahindra Scorpio P1832 Possible Solution :
The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

You can look up the code on www.bluejag.co.uk The problem is an O2 sensor (Bank 2 Upstream)and there are also details on the site about how to change it.
Fairly simple job

That P1647 fault code is for the upstream oxygen sensor on bank 2. This is the top sensor on the front exhaust cat converter. The usual failure is the sensor itself but you should inspect the harness that runs under and clipped to the battery tray. It is the sensor with the gray connector
Driveability will not be effected at the present, but it should be corrected in a timely manner to prevent damge to other componets, such as the catalytic converter.

Good luck, i hope this helps & thanks for using FixYa!

Fault Code:- P1647 Indicates a Power-train fault


The fault is generally due to a problem in the Computer & Output Circuit area


Fault Description: ECM HO2 Sensor control malfunction -bank 2 upstream (2/1)

Action of ECM:- ECM Default:- HO2S 2/1 control circuit inhibited


After clearing the DTC, complete the Drive vehicle for 10 minutes
Check for a reoccurrence of fault DTC.

Possible Fault:- HO2 Sensor 2/1 heater failure HO2 Sensor 2/1 sensing circuit: short circuit to ground, short circuit to high voltage, open circuit ECM Failure

p1647 is linear o2 sensor control chip bank 2 p1111 is intake air temp sensor

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.
