Elantra XD (2001-06) :: Slight Jerk And Quick Decrease In Speed For A Second - Error Code P1505
Apr 6, 2014
I have a 2005 hyundia elantra, i just recently noticed mainly while I was driving on the freeway or at higher speeds when I let my foot off the pedal my vehicle would slightly jerk and quickly decrease speed for a second, I then noticed my engine light was on. I stopped at a free computer test auto shop (o' reiley's ) and the test stated trouble code p1505 code definition - idle charge actuator signal - low of coil 1.

I got off the highway today and was at a very long light, but enough time to feel my car making slight jerking movements and i saw the car raise a little over an inch.

I just had a ton of maintenance done on my 2003 Elantra. Spark plugs & wires, timing belt, drive belts, water pump, replaced coolant and replaced the transmission fluid. The spark plugs are NGK platinum as recommended in my handbook. As soon as the mechanic started the car after the tuneup, the engine light came on with a cam shaft sensor code. He said it went off on its own.
The engine light came back on when I started the car. There's also a major loss of power after coming to a stop. I have to floor it to get it to go anywhere above 20 mph after a stop.
The mechanic said that when he replaced my water pump the liquid splashed all over everything and he thinks he might have gotten something wet that shouldn't have gotten wet and that all will be fine after it dries.

I am currently about 1700 miles into what is a, planned, 11,000 mile road trip up to Alaska and back to SC. The first three days of driving everything was fine and I was getting 33 MPG. Today my MPG dropped down to 28 and in the evening my check engine light came on. The folks at PepBoys told me it was P0139 which I understand has to do with oxygen sensors and would affect my vehicle gas consumption.
If I drive about 21 hrs (Denver to Portland OR) to get to a place where I have a trusted mechanic and more free time, will it be bad for the car/engine?
Driving: Elantra GLS, 2003. Around 53k miles on it. Just replaced the tires last week as well as all belts (including timing). A few years ago I recall a similar error and my mechanic had me take the car to a muffler shop to cut something out and reweld it. yeah, I have forgotten the details.

My MIL is on!!!! I went to Autozone, they told me the error code is P0121. The car is running funny, with uneven idle, and bucking/not shifting.

The other day, my Explorer gave a hard jerk while changing into 2 (maybe 3rd?) gear. Never happened before. I was under 20 MPH & had just stared it. (My speedometer works as do all the dials.) My Check Engine light came on & when I had the code pulled it read quote "P0715."Transmission Speed Sensor circuit condition. Vehicle speed above 15 MPH while transmission output shaft speed below 60 RPM. Possible cause Failed transmission speed sensor or electrical problem"
I got a Transmission Speed Sensor, (which I haven't put in yet), and was told that this would solve the problem. My question is twofold: Is there ANY chance this is a false or misread code and the problem is something else? And could ANOTHER sensor attached to the transmission be the cause? (How many sensors are on the tranny?) All I've read about this problem, say's replacing the Transmission Speed Sensor is preceded by the SPEEDOMETER quitting, but mine works fine.
The truck is a 1997 Explorer 4x4, but I don't use 4x4. In fact I've driven it without the forward drive shaft ever since I had the BW4405 Transfer Case replaced.

I have a 2003 Elantra GLS. I am intermittently Check Engine light and error code is P0113 - Air Intake sensor issue. I can't locate where the sensor is. I don't see any wire coming of the tubing that connects the air filter to the engine.

So I am getting a CEL and p0501 (Vehicle Speed Sensor) code and don't quite know how to approach it.
Other forums/posts suggest that I check or replace the input and ouput sensors on the transmission, but from what I understand those are each a unique code, and the p0501 is for a sensor located on the transaxle. Is this the case?
I was under the impression that because my car did not have ABS that I did not have the latter sensor on the transaxle, only the input/output on the transmission. If that is the case, will replacing both eliminate the CEL/p0501?

I have been hearing the squeal when turning wheel all the way to either side for a while. Recently I changed all drive belts (incl. steering). Squeal started to get worse and squeal when I turn the while just a bit while stopped or pulling in and out of parking spot. I tightened the steering and alternator belt and did not work. I flushed the power steering pump and added new fluid and still won't stop.
Does it mean need new pump or problem with rack? Or is there a possibility for some other "quick fix"?

My 2006 Volvo S60 turbo has about 116K miles and noticed a couple times when I punch the gas to accelerate quickly (like to pass someone on the interstate) that it will make this quick jerky thing (as though I ran over some rumble strips). I normally drive like a grandma so this has only happened a couple times. Today I was on the interstate and decided to test this out and sure enough it would quickly bump-bump-bump before the gas/acceleration kicked in. It never stalled, but now I am paranoid.
Also, it occasionally "feels" like it takes the car longer than normal to start. There is no pattern to this. It will happen first thing in the morning, but I have noticed it more often when I stop to drop my son off and get back in the car. I will crank the key and the RPM dial will shoot up twice really quickly and then be normal.
Maybe you should also know that when I first got the car, I filled it up with gas and started driving and it died. We checked the fuses and the fuel pump fuse had burned out so we changed it and all was right again.
I bought this as a high mileage car (60K) in 2007 and have not done much to it since (air filter, oil, tires, brakes). Yes, that means I have not gotten my transmission fluid changed or any recommended dealer maintenance.

I just bought a 2001 elantra. The car frequently will jerk or stutter while driving like the gas is bad or it is starved for something. When the stutter problem happens while driving the check engine light flashes but does not stay on. It usually only stutter 1 time but has as much as 3. The other day when I was in a drive thru waiting to order the car kinda sputtered during an idle then shut off the check engine light did not flash at this time. It restarted fine after that.
I pulled the codes and read them and I have 2. I am not sure if they are related to this problem. They were U0D00 and P0705. For the P0705 I cleaned the terminal but did not pull the negative on the battery the reset the computer. I reset the codes and the problem still is happening but no new codes are present. The code P0705 has not returned since.

Since they replaced my transmission at 40,000 miles, I've noticed that occasionally, but not always, there is an unusual quick half second jerk or jump feeling when I first crank the car on a cold start. It doesn't happen all the time, just some times, but it has to be a cold start when I do feel it. What this could be? I'm thinking maybe some bolts weren't put tight enough when they installed the new transmission?

New here. I have a 2001 F150 which i love but lately has been an issue. I started it up a few weeks ago after it set over night. i threw it in to reverse and notice it hesitating while reversing and it has small trouble accelerating but does buck and jerk while trying to maintain speed. So I took it to my well trusted mechanic and he ran compression test and ran the highly prolific OTC scanner on it and nothing. I have changed my mass flow sensor and I dont show any misfires or any codes pending. I did replace a busted catalytic convertor a couple months back. Im running out of places to turn.

I have an 06 sport edition with 83k miles. Never a problem or complaint. If I'm not going crazy, I think that I am noticing a very slight performance decrease. I bought this with 63k miles on it and I'm not 100% sure what servicing was done before. Where to start, spark plugs or something like that?

About 3 days ago I noticed my engine RPM was around 250 higher than usual. Usually my truck idles around 550-600 rpm (I know this is low). Anyway, yesterday it threw the P1506 "IAC over Speed Error" Code. It is idling very rough, shifting weird, but does crank up fine.
My truck is now at 93,000 miles and I just cleaned the IAC at 87,000 miles due to the common no start condition. I guess I am going to get a new IAC now since another code came up.
Well, my question is it came up with two other codes also:
P0171 - System too Lean, Bank No. 1
P0174 - System too Lean, Bank No. 2
Do you think the P1506 (IAC Code) made the O2 Sensor codes show up or is it really the O2 Sensors? I just changed my two upstream O2 Sensors around 90,000 miles. Should I get a new IAC or try to clean it again?

Ok, ready for a new head scratcher? After replacing the starter, the battery cables, the camshaft position sensor, several hoses that were broken and/or disconnected, a wire for the transmission "forgot the name of it, but technically it was a cable with a piece of plastic that connected to the throttle", air filter, spark plugs, spark plug wires, battery temperature sensor, ignition coil, several missing fuses, I got a new code.
This code came up and I believe it is the same code that came up before, but I think it got masked by the battery temperature sensor and the "random cylinder misfire." It only appears when I reach speeds of 60 mph or above, the code is P1899 and when I took it to Autozone, Oreilly's, and Dick Poe Dodge, they were unable to figure out what the code meant.

1999 F150 4.2L 125K miles.... My problems started about a month ago. I had a P1506 error. The engine was running fine but received the error code. I replaced the IAC and the air filter. Engine still running fine. A week later I received a code for the Intake Air Temp Sensor (don't remember the code). The engine still running great. I bought a new Air Temp Sensor and noticed the wires from the Air Temp Sensor were rubbing against the belt and had been severed. I made a mistake when replacing the air filter of not checking the wires (confession is good right).
The engine also constantly ran a fast idle 2000 to 2500 at this time. I repaired the wires. The engine light went off and idle now starts great and smooth but when heats up will will go to 2000-2500. I then decided to replace the Air Temp Sensor hoping to fix idle problem. Engine still idle fast when warm. However, when I come to a stop and put in neutral the engine will take a minute but go down to normal idle after sitting. Engine light stayed off for a week. Now engine light back on with original code P1506. Idle is still not working correctly.
I feel like I made it worse than it was originally and not sure what to try next.

I have received the error code P1506 on my 1999 F150 which is I believe an idle air control overspeed error. It seems to run a little rough at idle but not too bad. At the advice of my Haynes repair manual and the advice of a friend I have already replaced the IAC valve and the PCV valve on the engine and cleared the code, only for it to come back again after 50K miles. I am not sure where to go next with the diagnosis/fix.

I just received a 2001 Town & Country from my mom. It has 110,000 miles on it., Well taken care of vehicle. But...I've noticed a problem while I'm driving it. If I let off the gas a little the car has a couple slight quick jerks....at first I thought it was just letting off the gas but today just driving "normal" stretch of road I noticed it jerking while accelerating a little. Has a lot of pickup but what is this???? Is it the transmission??? Is it something in the engine. I don't know where to begin to take it...repair shop or transmission shop. What it could be??? All fluid levels are normal and normal color.

Since I got Prius I've noticed that driving at 50mph returns 80+mpg , 90+mpg if I let it gently glide at -1mph per 1 mile. As it gradually slows down, the mileage starts to decrease. By the time I get down to 45 mph the mileage shows around 70mpg,
I get down to 40mph, I'm only getting 50mpg. When I keep my speed between 40 and 45 I get about 52-55 mpg for the day. If I keep my speed between 45 and 50, I get 55-60mpg for the day.

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.
