Accent LC (2000-05) :: 2002 - Idle Varying Between 600 And 2500 RPM / Code P0507
May 26, 2012
Granddaughter showed up with her '02 Accent idle varying between 600 and 2500 rpm. Disconnected Idle Speed Control Actuator and engine runs at very high idle so apparently the ECM is unsuccessfully attempting to manage the idle and the ISC is functioning. Reading P0507 code. Checked for vacuum leaks beyond throttle body, found none.
The car was involved in a fender bender accident a couple days before the idle issue. No CEL until a couple days after the accident. The varying idle started many days after the CEL.
The wreak cut a half dozen wires in the area outside of the battery. She repaired them and I just finished redoing with solder and shrink wrap. Found no faults with her twist and tape repairs or any other damage to wiring. Varying idle still there.

I have a 2002 Accent 1.6L 72K miles, idle surging between 1500 - 2500 rpm after stopping from 50 mph, (with Code P0121) replaced TPS - No Luck . I reset the DTS error codes, ran it with a new TPS and same exact problem, Code P0121 came back, and surging continued, this happens when I decelerate from high speed- 50 mph or so and it will not go to normal idle, surges between 1500 and 2500 rpm when in park.
If I give the throttle pedal a good kick, the problem goes away, and it idles fine, nice and smooth and at normal rpm, the DTS code will clear, and stays cleared, mil light goes out. It almost seems like something is sticking, I know its not the throttle itself because when I do a live data, the TPS shows "0", if I manually push the throttle shaft closed at the throttle body, it is fully seated shut, so I know its not a sticking cable or anything. Can a sticking MAF sensor cause this? Maybe what I'll try tomorrow is rapping the throttle body with a rubber mallet while its surging, maybe something is not returning to its normal position in there.

Air Conditioner Blower Motor on any speed, lets say high. Running fine while driving. Come to a stop at idle or shift to N or P. A few seconds later the blower begins to vary its speed in pulsating rhythm in what would seem to be in cadence with what would be a rough or varying idle. Where to start? Is it the relay?

Having DTC of P0507? Engine is revving a bit higher at idle than normal.

08 Accord. After replacing the starter and cleaning the throttle body I keep having a CEL and the P0507 code.
Checked for leaks around intake, vacuum lines, etc. found none.
Tried the relearn procedure and still no luck. Car idea higher than normal ( just over 1000 rpms warm). Also feels like it wants to pull even when stopped.
So I figure I have either:-damaged the throttle body somehow cleaning it- Have incorrectly implemented the re learn procedure- missed a vacuum leak ( possible but doubtful)- or something else I don't know about

Ok had a check engine light. It directed me to replace the IAT sensor.. After some research I found it was integrated into the MAP sensor. Purchased a new sensor and replaced. Drive about 15 miles CEL throws another code. P0106 (sensor i just replaced) faulty Map sensor.
Followed procedure to replace sensor.. unhook battery cable reset ecm. After reset engine is hard to start. Followed by RPM changes (assuming its the ECM re-adjusting). Then CEL flashes 5-6 times and goes out, Drive 15 miles. Map sensor code reappears. (note i only purchased one sensor But repeated install 2 times).
My thought is against wiring. since the codes refer to different signal wires one for IAT one for MAP sensor. Faulty replacement sensor?

I just replaced the front and back motor mounts on my 02, 1.6 automatic accent. The front replacement mount was 1/2 inch too wide at where the bolt goes through, but made do. Now, the idle, but that's it. Before, it was vibrating somewhat at idle and lots of steering wheel vibration at highway speed. Now, I have no vibration of the wheel at highway speed, so it's like I eliminated one problem and made the other worse. I am hoping that the mount being too wide is the problem as I ordered the correct one. While taking it apart, I also noted the bolt through the front motor mount is incredibly small compared to the hole and this was true on both the original and the too big replacement. Why is this? Assuming that I swap out the too big mount for the proper and it still vibrates, than what?

I would like to know if for the Accent 2003 there is a component that commonly fails and causes a P0108.
Vacuum seems to be ok. At least I can't find any leaks. Pressure at idle is normally at about 30kPa (4.3PSI). It ranges normally between 30 and 50kPa (7.2PSI). When the fault was set it indicated 125kPa (18PSI).
Sometimes the engine runs unstable at idle.
It seems to be an intermittent fault. If I clear the fault it can take about 2 days to reappear.
Otherwise I will have to go through checking the MAP sensor itself, wire harness, idle motor, is that about right?

2002 HD 2500 6.0 - Pulled into Wal-Mart, everything was fine. Came out 20 min later, started right up, but felt like it stalled, it was actually still running, (barely). Shut off, restarted, same. Used pedal to bump idle up to normal 500-600 RPM, it was smooth, no misfire or roughness. Drove home, approx 5 miles, and had to keep the idle up at every stop.
Could be IAC? How can I test it/What checks can I do in the darkness, by flashlight? No garage, but I do have tools, and basic test light, dmm, etc. First thought was fuel pressure, but it runs fine going down the road.

I have a 03 explorer sport trac. I am getting code p0507. So someone told me it the Mass air flow sensor. so i went to the auto store and pick up mass air flow cleaner so the light went out for 3 day .now it back on again no air leak that i can see. Not saying there is none. Now someone telling me it a egr .

I was looking for some diagnosing the problem with my car. I've already gone and put one of those autozone scanners on it, and it gave me a very vague idea of what could be wrong. It pulled a P0440 and P0507 code. I go to work and school full time so I don't have the time to be poking around at everyone of those possibilities.
The check engine light came on a few months back, the acceleration has been bad since then, but it just recently started running worse. While accelerating the car jerks horribly, but then will smooth out if I give it more gas or let off a little bit.

Car started idling all weird this evening, rising and falling when at a stop light. Car APR Stg 2+. Found the fault code above. I changed the map back to stock and cleared the code and it still does it. I let the car sit for like 30 minutes and started it up again and it sounds even worse like it wants to stall. I did a few google searches and it seems that it could be a faulty PCV or throttle body. How should I proceed? I'm thinking change the PCV and if the problem is still there it's a potentially larger issue.

When I bought the car a few weeks ago, there was a p0507 code for a high idle in park, about 1300 RPM, but sometimes shooting up to 3000 when I shifted into park and then dying down. The code goes on and off intermittently. Not that big of a deal at first. Then I started noticing that if I revved it in park it would take forever to die down to 1300, and sometimes would fluctuate around 2000. I also noticed hesitation while accelerating around 1500 RPM and the transmission hunting for gears while accelerating, as well. I noticed my throttle cable was very slack so I tightened that, and bought myself a throttle position sensor, thinking that might be the problem, but didn't install it yet.
I was driving on the freeway yesterday in cruise control and then I started losing power while my foot was on the gas. With my foot on the gas, the throttle would cut out every second. I was basically one second of throttle, one second of no throttle, all the way down the highway. Almost impossible to drive. This continued even after I turned cruise control off. I limped my way to Home Depot and installed my TPS in the parking lot, and drove most of the way home with no issues, although I still noticed a slight hesitation while accelerating. Alas, I tested cruise control again and then the throttle on/off problem started again, then I could barely drive the thing, even after cruise control was off again. I'll be returning the new TPS to Autozone today, since apparently that's not the problem. What's my next move?

I have a 1998 blazer 4x4... I had a issues with the car before and I had to turn the idle screw up until I fixed my problem. I now fixed my problem and I need to know what my idle rpm should be at.
After I fixed the original problem after about a day of driving I had a P0507 Idle speed High/Low. I turned the set screw down and lowered my rpm. After about 5min of driving the code went away on its own.
About 1 week later I am now getting the P0507 again and now it has a buddy. P0446 Evap System.
Questions what would my idle rpm be? Can the high rpm cause the EVAP code as well.

Saturn 2002 SL1 5-speed. My SES light has been on constantly for about a year (was intermittent before that) with the codes P0172, P0300 and P0507. The car also idle high (2500+) occasionally at stops. My mechanic said it is likely an intake gasket but would need a full diagnostic to determine and that is not a safety hazard to drive but that I am getting less mph. I can't afford to fix it now but I have an emission test due. Is there a way to turn to light in the mean time?

Recently got broadsided (passenger), got the body fixed up. Now it is Misfiring on idle and only on idle...
Prior to this I had Coil go out on me, got that changed out, changed the spark plugs. It was running great then the accident happened an this Misfire on idle problem.
Took it to the shop, had them check for a code, no code. They suggested that it made be do to carbon buildup from the previous misfiring issue and suggested using STP engine treatment on it.

I have a 2003 Accent with the 1.6 DOHC.
It has been fine, but now it is acting up. Car has about 90,000 miles on it. The engine will start fine, hot or cold out. Sometimes the car will idle fine and warm up, sometimes it will idle for a few minutes and then cut off, will not restart until engine cools off. No, it isnt getting hot.
You can start the car, keep your foot on the gas a little to keep it above 1000 rpm or so, and it is fine until it warms up. If you start the car, go a 100 yards and take your foot off the gas it will cut off and not restart until the engine cools.
I replaced the ISB or whatever that thing is called, no change. No check engine lights come on at all. I took the throttle body off and cleaned it with cleaner, seemed to work ok for a day, then the same thing all over again.
What should I check now, very frustrating, but the little thing gets great gas mileage.

I have an 05 accent that overheats on short rides, it smells of antifreeze when you pop the hood. There are no visible leaks, and the antifreeze level is good.
Also the check engine light is on and is outputting a P2096 code.
I'm stumped as to what this problem could be, at first I was thinking thermostat or some kind of clog or something like that, now I'm not so sure.

2004 Accent - auto. - 100K miles
CEL for code P0304. I thought I had it solved but now it comes on after every fuel fill-up. Its happened at least 5 times or more. I know what the code means (ign. misfire #4 cyl.).
I read and checked what affects the code but this one has me baffled. I thought at first it is the evap. canister but the car takes a fuel fill-up without any trouble and it is not hard to pump it all in and does not give me the code. If I put a bottle of STP gas treatment in the tank it clears the code after about 40 miles driving but it doesn't explain why it sets off the CEL on every fill-up. I also thought I may have sediment in the tank and the fill-up is stirring it up but I have filled her up and various capacities. Also, several weeks ago I got the CEL code P0441 for the purge control valve. I replaced it, cleared the CEL and it never came back on. Fuel filter has never been replaced because it is built into the fuel pump assembly.
Overall drivability and MPG's are not affected.

I have a 2000 Accent with about 150,000 miles on it. Recently I have noticed that when my car is sitting in an intersection, the car appears to idle roughly. I would't exactly say that the car is idling rough, cause it stays at a consistent RPM while in drive or park, but the engine gets louder and the steering wheel starts to vibrating. When I slightly step on the gas, the vibration goes away. Also, when I put my car in park or neutral, the car quiets down and the vibrating stops.
I was wondering if it could be the throttle position sensor, or maybe a broken motor mount, but I haven't had a chance to look into it it. I did replace the purge control valve last week, which slightly improved the vibrations.

2004 Hyundai Accent has is misfiring, after warming up, only in idle. This only happens after about 30 seconds in idle. Could it not be getting enough gas? This being said I was getting misfire on 3 as well but that would happen all the time and cause the entire car to shake. This problem is now fixed and only #4 is causing me problems.
