First I would like to think joycesjag for the awesome write up and everybody else that give me advise.... Yesterday afternoon i started working on project P1549 (bottom IMT to clear thing up on which IMT the ob scanner code referring to) it took me about 20min to reach both IMT. When take out both IMT I notice the both had the new green O-rings, so i started lookin for other problems and i notice that the bottom IMT connector one of the wire were ripped off. Due to lack of supply (please don't Judge) i connected the wire with an extra electrical wire an tape one end and stuck the other end to the metal rod of IMT connector an tape it with electrical. I did't bother to replace the o-rings, an i put back everything together. i Drove the car last night now i'm i gonna run to autozone in the morning see if the clear the IMT code 1549. if this work, i will only have to worry about one more obd scanner code P1646 HO2 Sensor control. ill let yall know of the out come later this afternoon.

 

Hi again, I Just brought the Ho2 sensor can you please tell me by looking a the pictures which side is the sensor located on the motor that throwing the check eng code P1646

 

Don't know the engine well but I can say you have Left & Right swapped in pic #1.

All directions are as if standing behind the car looking forwards.

 

\
Pic 2 and 3 pic are the same picture just one is in focus more also that the left side of the motor.

 

cel,

Your passenger side is the right side as JagV8 mentioned. Pic 2 and 3 would be the sensor that is supposedly bad.

 

HI again it been over a week since i replace the sensor and the check eng light is still on. Do i have to use OBD to reset the light ? or is suppose to turn off by it
self?

 

If fault fixed MIL goes off soon. If still on, same or another fault.

Read codes....

 

Now im getting upset i replace HO2 sensor and reset the check Eng light. IM still pulling P1646 p1000.

is there anything im not doing right or for getting?

this is the oxygen sensor that i replace it Brand New Oxygen Sensor Walker # 250-24439 | eBay

 

Make sure you look them up in the codes PDF as that explains them.

Sounds so far like you replaced the wrong sensor or with the wrong kind but as I say read the PDF.

 

HI guys

It been nearly eight months since i buyed my jag and i'm very with happy with it. i've been fixing it up little by little. i have two check engine light that have been occurring and i can't get rid of. (P1646 and P1000).
P1646 `
OBD II
ECM HO2 Sensor control
bank 1 upstream (1/1)

i spent nearly 300$ i replace both driver and passenger H02 SENSOR and still i'm pulling the same code. Is there anything else that causing these errors! the last thing i wanna to is go jaguar dealership.

P1000 OBD Systems Readiness Test Not Complete

I'm not sure what this mean!!!!!!!!.

CAN SOME PLEASE TELL ME WHAT IM DOING WRONG ?

 

edit: I see you posted this before here https://www.jaguarforums.com/forum/s...urchase-68490/

(not sure you're helping yourself by reposting)

Get JTIS. Look at its codes PDF for your car. It explains P1000 in detail.

Also explains the ways P1646 can occur. Did you check all of those yet?

The wiring may be awkard to do but you don't want to assume the worst!

 

As you have found out just throwing parts at it does not work too well. Do some searches on this forum. The V-6 has a list of known problems. But the good thing the cost to fix is not bad if you can DIY.

Otherwise owning a Jaguar can get pretty expensive!!
