Is this an automatic? P1527, Basically, the tcm is telling the pcm to turn on the lite. You could have tranny problems? Could be issue with transmission range sensor? I saw a service bulletin, kt2007020701, that is a relearn procedure, if the pcm--tcm or transmission has been replaced. I don't know if relearn will help or not?

P1529 and P0720 does not seem to be understood.

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

P0118 means Engine Coolant Temperature Circuit High Input.

Check with the place that checked the codes for you. Maybe they can test the IG sensor for you. That might help. Otherwise check all the connections relating to the sensor.

No, O2 Sensor would make your van to be none fuel efficient at least or won't change anything if it's the O2 Sensor or Bank2 ( It mean's the 2nd one, the 2nd one is a dummy.. it just read what's going out from the catalytic converter and tell's the computer if there's a change since the reading of the first 02, so the computer see if or not the catalytic do his job ) For your Jerking and Jumping problem.. those Gm Van has alot of transmission problem and maybe your transmission on a way to take vacancy or it is just missing oil ! Check Oil first, for that do that when the Motor is Cold, Start you Van Leave it in "Park" Position, Pull the Dipstick of your transmission ( Should be the Red one ) clean the end of it with a Rag and put it back, pull it a gain and check if the oil is in the reading, if not add the missing oil while the motor turn's, and recheck it until it's full ! Otherwise if the dipstick show's Full, Here's a tip's go to your local autopart's supplier or store that sell's car product such oil's, coolant ect.. ! Buy a Bottle of : Lucas Transmission Fix, Remove the Transmission Plug, and remove about the half of the oil ( Not the Whole amount of oil, only the half it's important ! ) and put the plug back well tighten, pull the dipstick and add oil from the dipstick tube with your bottle add about the half of the bottle, start your van, check the oil level if it still missing some oil add the amount it require to be full ( While Motor is Turning ) ! Important do not Overfull the transmission ! This Should Work or not, if not.. I would say you need to Replace your Transmission, What I told you is about 15minutes of your time and a couple of dollar ! Best thing is to bring your van to a Transmission Shop they will tell you the problem !

My car jerks going down the road its a 95 Buick century and it changes gears fine when I take off just stares jerking a few days ago


When you say it "jerks," this description could fit several actual symptoms. If by "jerks" you mean the engine misfires, it could be caused by the need for a major tune-up (including plug wires and distributor cap), or it could be a problem with fuel delivery, contaminated fuel, or defective components in the fuel system.
I assume the CHECK ENGINE light is on (and has probably been illuminated for some time now). Begin by doing a readout of the stored codes, and use the results to begin your diagnosis.
If by "jerks" you mean the transmission is slipping (engine revs but car slows down or doesn't accelerate), you have a transmission issue. If the transmission fluid and strainer/filter have not been replaced within the past 5 years or 50,000 miles, have a complete transmission service performed.
If by "jerks" you mean that the steering wheel wobbles or pulls, you have a problem with the front suspension.
If by "jerks" you mean that the car shudders or pulls when you apply the brakes, you need brake work.
I think I covered all of the "jerks." ;)

Golf FSI 2.0 (2005 Model) Automatic golf. The Car stats Jerking when changing gears especially from second to third gear whats the problem?


You may need a tune up . When was the last time you changed plug wires and had a decent tune up that will cause a vehicle to jerk when reaching higher gears the more strain on the engine the more it will jerk!!!

Pt cruiser jerks when acclerating, hesitates when not accelerating, fine when idle


I am not saying this is the solution or this is the problem but the PT cruiser suffer from code P0344 Which is the cam position sensor which causes misfire, the solution is a reflash of the ECM.But before a reflash the Camshaft postion sensor needs to be verified for working condition and if possible duplicated.Once the Check Engine light does come on you automatically go to limp home mode, This is the drag that you experience,the purpose is to protect the catalytic,in case there was a true condition with intermittent cam postion sensor,You need the check engine light code, then you can go from there.

"car jerks/jumps"


These is because of the improper combustion, so you better check the air filter and the exhaust along with that you replace all the spark plugs
