*updated at end of post

I have replaced my Clutch and trans. on my 2003 x-type 2.5l v6.
With these error codes (AT BOTTOM OF POST *UPDATED*)
Just before i replaced trans and clutch, i had some slip from worn clutch and motor hesitation. Now that we have replaced worn clutch and trans i have exelent grip from the replacement but still i have a major drag on engine or engine is hesitating to accelerate more noticble to bigger loads on engine climbing to higher gears and speed any suggestions? (Limp mode/Reduced Power..

 

Unseen, well, your P1647 code is telling me that the computer is not liking what signals the Bank 2 (upstream) O2 sensor is putting out. Fortunately for you, that sensor is located directly under your air filter for the engine. So, I would first do the idiot check and make sure that it is plugged in. From there, you may be looking at having to replace that sensor.

As for your P1145 code, from what I can tell, Jaguar does not use that code for their engines. Are you sure that it wasn't a C1145 code? That would indicate that you have a wheel speed sensor issue which could be leading to an inappropriate application of your brakes if you have dynamic stability control (as it would be seeing wheels spinning in relation to a wheel that isn't turning). But, I am going out on a limb with that one.

As for the P1000 code, that is just saying that the ECM has not been able to complete a drive cycle and not get any codes.

 

advanced wrote the codes down for me he actually wrote B1145 wasnt sure because of his handwriteing ...

okay well when i get out of work today ill take the air fillter out to get the best viewing angle on it and disconect and clean contacts
do i need to get advanced to reset the codes to see which ones pop up again or whats your suggestion on that?

as far as th p1000 my abs light is on.. and i do change my brakes myself what could cause that?

 

Unseen, if your ABS light is on, then odds are it is the C1145 code. That is for one of the wheel speed sensors which is used by the ABS computer (hence your ABS light).

As for clearing the codes, if you have the radio code (4 digit number on a card), then I would say to pull the cable off of the battery, wait 5 minutes and then reconnect the cable. This will clear out the memory in the ECM, giving it a chance to relearn everything. If you do this, it may force you to enter a code into the radio (hence the card) and you will have to reset the auto up/down feature of the windows (with all windows up, doing this 1 window at a time, press and hold the button to lower the button, keep holding after the window reaches all the way down for another 3-4 second, release, raise the window by holding the button up and let the window go fully up, holding the button up for an additional 3-4 seconds, repeat on the other windows). After that, if you are getting a code, it is something that is still in the car.

 

whats a good way to see which sensor for wheels is malfuntioned because all 4 sensor will be pricey..

and as far i do not have the code to reset.. would jaguar be able to acquire that number again?

thanks for your time and help
it is veryy appreciated

 

Unseen, yes, as long as the parts guy didn't clear the codes, then all is good. Even if he did, you still have the light, so, there is at least 1 code in the computer.

 

Okay, so in the past couple of days i have bought O2 sensor. Installed and got advanced to reset my ecm everthing worked for like 30 min with no engine light just abs light lit after that engine light came on and wont let me pass 3X1000 rpm on any gear so i went to advanced to reread what check engine codes were present codes read as is in order C1145 and still P1000... the advanced auto parts tech said it was a manufacture code and does not have definition for c1145 but the p1000 was telling me that i have a lean system what should i do from here i have invested quite a bit and do not want to sell this vehicle i have replaced rack and pinions clutch trans power steering and water pump with various sensors.... before i reset the ecm one code was there that wasnt before and i did not get a chance to write it down but the definition stated that a cam sensor sent that code again i appreciate all time and consideration put forth to answer these questions

 

last post was a lil sloppy so just to restate question is why is the p1000 still lit after i have changed faulty o2 sensor ?? and what do i do from here lol

 

i it has any info to add while there was no codes and i was driveing hwy when i did pass 3k rpms as accelerating to 4krpm and higher i feel the engine rock almost if a missfire was present or even if timeing was off which brought a curiosity when i saw a cam sensor code

 

if**^

 

Sitting here on the other side of the Pond, I find the writing of posts with no punctuation a curious and interesting challenge!! So Unseen, going solely on the reported codes, here's my four pennyworth: Code P1000 is nothing to worry about; it just means the engine has not yet been driven through its full system check since the codes were last cleared. However, it does mean that by the time it has, there may be another fault code recorded - time will tell. (Lean system - Rubbish!)

C1145 is a righthand front wheel sensor circuit fault - loose/dirty connection or maybe a chafed wire as the suspension moves up and down.

If the engine is in 'limp home' mode/limited to 3000rpm, then there must be another fault code - a faulty Cam Sensor (One on each bank) would do it! They're not difficult to get at and change if required or check for a connection problem.

 

I have finally gotten a fellow to find more codes than anyone so far the codes read as follows in order as scanner read....

P0171
P0174
C1145
P1000


i have checked o rings on the vacuum lines connected..
trying throttle body cleaner, Mass air flow sensor cleaner, And going to disconnect and use electrical contact cleaner today will be back with results.

Help

 

Cleaned MAF sensor, cleaned throttle body, disconnected all electrical connection and cleaned both male and female adapters. Used full fuel system cleaner.

Still stuck in reduced power, but engine is idling slightly better.
Any ideas?? Fuel filter??
