Question about 2002 Jaguar X-Type
P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)
This sensor signals the engine-control computer when detonation is detected, momentarily retarding ignition timing until detonation ceases.
Most computer-controlled systems use knock sensors to ****** timing when the engine is experiencing pinging or knocking.
Obviously, a faulty knock sensor produces problems that appear to be ignition-system-related. If the knock sensor system does not provide an engine detonation signal to the PCM (powertrain control module), the engine detonates, especially on acceleration.

I had the same problem and found that the PCV breather hose was leaking, creating a vacuum leak. The codes for the error that I received have translated to "bank 1 too lean, and bank 2 too lean." Start with the PCV breather hose and see if that doesn't fix it. You will also have to reset the ECU afterwards to get rid of the error.

I have a 2002 X type (2 litre. done 44000 miles), dash showed gear box problem, (red circle light up). I pulled out and turned the engine off. 5 minutes later turned the engine on. The engine running but the car would not drive either in drive or reverse. Turned the engine off again and on the car driving but not much power. The care is taken to the Jag. dealer and told is misfiring + some gear box faults. Suggesting to change some coils and see (cost about £200+). also possible need to change the gear box costing about £2500+. Please advice. Shall I go ahead with the repair? Should I part exchange.

SOURCE: Hesitation in engine
There are more than just the two causes listed by Jigsaw_9077. I also have a similar problem with my '02 Jag. s-type 4.0L. Very rarely will airflow cause a "miss-fire like" hesitation unless there is a complete blockage of airflow (such as a broken valve or something of that sort) and will most likely ALWAYS have that hesitation, just just bellow 1500rpm. Richard_drin is partially correct. Fuel can cause this hesitation and commonly at lower RPM. If there is a fuel issue, a new fuel filter or a fuel rail/fuel injector flush should help or fix the problems unless there is an electrical problem with the fuel injector or the fuel pump is bad (a fuel pump problem is normally at higher RPM). The first step to finding the actual problem (because it can be one of many) is to change the fuel filter. If the hesitation is still the same, have a mechanic check for proper fuel pressure. This shows if your fuel pump is operating correctly and your fuel lines are not obstructed. If it is determined that there may be an ignition problem, like a check engine light with a miss-fire code like mine is doing, then find the cylinder with the miss-fire and and swap the coil pack with another one that appears to be working properly. (ex. miss-fire code on cyl. 5, switch the coil pack with the one from cyl. 1 and clear the code) If (or when) the check engine light comes on again, have it scanned for the miss-fire code again. If the miss-fire is from the same coil pack, replacing the coil pack should fix the problem, if there is a miss-fire from the same cylinder as before, then you know that it's some other ignition problem. Now you have narrowed your problem greatly, and haven't spent any money on a mechanic (or parts if do the work on your own car like myself). This is where I am at with my car right now, but I have not yet found the solution yet. When I find it, I will update to give you more info and save you from paying a mechanic for doing all of this research for you.
