You say you changed the cam sensor. A1391 code is a crank sensor on the top of the trans. bell housing.

SOURCE: Jaguar xk8 1997 The throttle

My throttle body problem was diagnosed by the local Jaguar dealer (Barrett Jaguar in San Antonio, TX). They wanted $1200 to fix it. I had read on the internet that the throttle body should be cleaned out first because that could be the problem. When I asked them if they could clean it first to see if that is what is wront they told me that it would not do any good. It was an electronic problem and the whole thing needed replacing. I had my brother-in-law who is a mechanic clean it out for us and reinstall it. We have had no more problems. Can you believe I got a coupon in the mail yesterday from Barret Jaguar for a $143.50 throttle body cleaning special!!!!!! Liars all of them! Don't trust your dealer to tell you the truth! They just want as much money as they can **** out of you.

Is the throttle sensor located at the accelerator pedal in a 2012 Jeep Patriot, Latitude (with 2.4 liter engine & automatic transmission, front wheel drive)?


There is one at the pedal and one at the throttle body. The one at the pedal tells the computer what throttle you want, and the one on the throttle tells the computer where the throttle is. Usually, if there is a fault code for the pedal sensor it will say "sensor A" and a problem st the throttle body sensor will say "sensor B", but not always.

P0011 when cold but I can clear the code and it runs fine for the rest of the day.


More often than not it is the crank sensor that is causing the issue. If you don't think that is the issue and you know when the check engine light comes on than it is time to scope the crank and cam signals to see what the cam is doing. If the cam is not reacting correctly than there could be an issue with oil pressure getting to the cam solenoid or getting to the phaser. If that's the case the only fix is to replace the engine.

Engine starts and idles fine, but will not rev up (2001 Jeep Grand Cherokee 3.1 diesel auto)


If it was a fuel shortage the engine would rev but to limited speed. This is a lack of air to throttle body. Check for clogged air filter and all the piping and the throttle body.

Hi.have jumped pushrod.are cam followers hydraulic and can they be removed from top with magnet or cylinder head have to come off.regards lenny .2.5 td


I don't see the answer I posted so here's the short version: the head does not have to come off. There is a better tool available to remove lifters it is an expandable "hook" that grips the inside lip of the lifter and has a small slide hammer on it so if lifter sticks in bore you can still get it out. Any dishing on business end of lifter indicates corresponding cam wear. If dished, cam needs replacement. also check pivot point on rocker and ends of pushrod for wear.
good luck
