I recently took my car to the Hyundai dealer who told me that my engine light was from a bad cam sensor (Fault Code = P0340). I bought the sensor from the Hyundai parts dealer and replaced it myself. After having the code erased, the check engine light comes back on (with the same code) when I turn the car off and turn it back on, after driving it for a while (30 minutes or more).
View 5 RepliesI have a 2005 crdi diesel santa fe that i have a strange problem with it starts up first time no problem in the mornings and can drive all day long. However if i switch it off and leave it sit for about a half hour no way will it start again until it cools off. It will start though with a push start instantly!
I got only one fault code P0340 cam shaft sensor fault, i replaces sensor and made no difference. Is this a common fault???
02 Santa Fe 2.4L/ automatic/2 WD. I replaced the fuel filter (only) and have had a nightmare ever since. It takes multiple tries to start, running a little longer each time. When it will finally stay running, only the most delicate of throttle feathering will allow any RPM's to be built up. Any attempt to do otherwise will result is sputtering, bucking and other unhealthy behaviors until the throttle is closed. It also gives off the smell of running rich.
I borrowed a scan tool and got P0136 and P0141, which I expect since the O2 sensor wiring was cut in two by the heat shield shortly after my daughter bout the vehicle. It also is giving me the P0340 Camshaft Position Sensor Circuit code. I had replaced the CMPS and its connector a couple of month ago. I replaced the sensor again to no avail. I have checked the Orange/Black wire from the connector to the ECM and it reads 0 ohms. I get battery voltage at the connector on the Blue supply wire but only get 1.86 to 2.0V when I check the signal with the engine running.
I have a 2005 hyandai elantra with 176k miles. ck eng light came on with P0340 cam shaft positioning sensor. I replaced it and cleared code and ck eng light came back with same code. So as last resort took it to dealership who replaced the wire from sensor to ecu and told me i had a bad ecu. I replaced it with a used one from a semi-reputable salvage yard (i mean i have used them several times with no issues). The code came back almost instantly. Symptoms of the car starts good cold within a few minutes it is very slow to accelerate and i have noticed a severe loss of MPG. I have also checked timing because i changed the belt in this process.
View 9 RepliesSo my wife was driving our 2002 santa fe 2.7L and it shutdown. I went with the scanner and saw one code, P0340. I towed it home, changed the Crank Position sensor, which really sucked. I put it all back together and still no start. Same code.

View 3 RepliesP0340 code appeared on my camry 07 said cam shaft position sensor was bad what other things can be the problem ? Also I just replaced alternator because car wouldn't start with out getting jumped once I replaced alternator it started up good for a couple of days then when I wanted to start it up it would crank then stop and crank again till it would turn on also car stereo would turn off while running and dashboard gauges would go off and would make the gauges go Dow to zero then it would go back to normal while still driving.
View 1 RepliesI am getting the code for the camshaft position sensor. Erase code, comes back immediately. I don't even think this car has a camshaft position sensor.. I guess the first step would be locating the little bugger. Crankshaft position sensor is new and seems to work fine. Car is running btw.

View 3 RepliesMy CEL is on and according to Auto Zones code checker read a P0340 on my 2002 KIA Sedona with 160400 miles. It said Camshaft position sensor A circuit malfunction 1 or single sensor.
So what should I do now? Van is running as smooth as ever so not sure what I should do.
1996 Ford Explorer on a small island with no mechanics. Vehicle does less than 100 miles per year, never over 20 mph. The check engine light came on and the code reader says it's a problem with the Camshaft Position Sensor. The vehicle runs fine, just as it did before the check engine light came on. I'm tempted to put some electrical tape over the check engine light and keep driving.
View 2 RepliesI am getting a p0501 code (off my code reader) on my 2001 Elantra. I have already replaced the Speed sensor on top of the transaxle under the air filter. Driving into work today check engine light came back on and took to AutoZone. They are getting a P0501 code Sensor "A". They had no idea which sensor, sensor "A" was. I know there are 4 sensors on this car and have searched for other posts with no luck, all say replace speed sensor. Need to get this done to pass emissions.
View 2 RepliesI recently acquired my dad's old truck. Its a 2002 Explorer EB 4.6L 4x4. Great truck, family owned since new. Recently it has had the service engine soon like pop up and its throwing code P0340. The mysterious cam sensor code.
May I ad that the sensor itself is new, OEM ford. I have just replaced the alternator (which is usually a common problem for this code), and still no luck. The car starts up, still runs great, and has had no hesitation or stalling.
My mechanic friend checked it out and said that it is getting some voltage, but not as much as it should? the wiring to the PCM looked good too. The Ohms on the CMP checked out good too.
I really hope its not the PCM on this car. I may have to just take it into the ford dealer to see if they can diagnose the car. I do work as a tech at a small indy shop, but currently dont have the time since i'm trying to finish my schooling this year.
I just want my car to be in tip-top shape...
I have a 01 elantra. Check engine light is on. Diags say p0133 o2 sensor slow bank 1 #1. Any way I have replaced the front sensor. Actually now I have 3 of them. The exhaust does not leak. New gaskets on the converter. New flex pipe and everything has been welded.
View 7 RepliesI 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 new to Hyundai. I just picked up a 2003 Elantra and I'm doing a couple fixes to it. When I got it, the engine light was on and the code displayed said it had a bad camshaft position sensor. Is this a common issue with the car and is it an easy fix?
Also, I just installed new brake pads and a new battery. Now the battery and brake lights are on, although I know I didn't break anything. Could installing a new battery cause the two lights to come on?
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?
2002 Santa Fe 2.4L Automatic. Driving on the freeway when it lost power. Couldn't go over 65 even with the accelerator all the way down, even slower on uphill climbs. The engine wouldn't rev higher than around 3000rpms.
I figured it sounded like a loss of power due to weak fuel pump. I replaced it as well as the fuel filter, and verified it was pumping. Put the car together, and still the same loss of power. Drove home and parked it, but next morning it won't run at all. It cranks all day long but doesn't fire.
So far, I have made the following repairs and checks:
-Verified catalytic converter was clear and not plugged
-Verified fuel pressure
-Checked spark plugs - all are good and gaped properly
-Replaced crank position sensor (With the code, I thought this would solve it)
-Verified timing belt and cam belt in time - both have also been changed recently
-Checked all relays and fuses
-Battery and alternator are good - both are new
I still have a crank no start issue, and I'm going crazy taking things apart and putting them back together only to have this car not fire.
So my mom recently bought a 2003 Elantra (75K miles, auto trans) and within a few days the CEL came on. She took it in to PepBoys and had them hook it to their scanner to get the codes out of it. The only code that came up was P0113 Intake Air Temp (IAT) Sensor high input. I've done a little research on the net but there is a lot of random info for this code out there. Is the IAT a separate sensor or is it combined in with the Mass Air Flow (MAF) sensor(if this car even has a MAF) or combined in with the MAP sensor? I've read on the net that it could be any of these 3, I think it's combined into the MAP.
I've also read that this code could be caused by a bad IAT, bad O2 sensor, an exhaust leak, bad wiring/ground(I checked the wiring/grounds visually and everything seems ok) or many other things. If it's as simple as replacing one of the sensors I can do that myself, I just don't want to go randomly buying things and either it be the wrong part or have it be the right part but not fix the problem. The car runs great, even with the CEL on. Yesterday when she stopped by my house I disconnected the battery for a couple minutes and reconnected it, started the car & no CEL. She drove the car for about 125-150 miles before the light came back on.
2003 Hyundai Elantra, 1975cc engine, XD. P0198 Error Code.
I know this is the Engine Oil Temperature Sensor High code and I have seen indications this may mean high voltage on this sensor. My problem is I cannot locate this sensor on the engine. From what I have read this sensor is supposed to be on the driver's side of the engine on the head, rear side.
On my engine the head was replaced (unknown to me when I recently purchased the vehicle). From all indications this is not a CVVT engine. The air intake has a MAP sensor that is connected and appears to be functioning properly. The driver's side of the engine does have two coils but I can see no other wires from the wiring harness toward the rear of the head other than leads to the starter.
The cam sensor is located on the passenger side of the engine, rear side. I have found the oil pressure sensor and crankshaft sensor on the front side of the engine block toward the driver's side. I have found and engine temperature sensor on the driver,s side of the engine on a housing connected to a radiator hose.
Oddly enough there was an OCV hanging on the harness toward the front driver's side of the wiring harness. Adjacent to this plug is a second plug on a shorter lead that is not connected to anything. Both of these plugs have two leads but are shaped differently oval for the OCV and the other is rectangular. I am wondering if this rectangular plug is for the engine oil temperature sensor? What I cannot see is where the temperature sensor would screw into the head on the front driver's side (near this plug).
I went to NAPA today and they do not have an engine oil temperature sensor listed, but I was able to find one on line. I cannot find a connection point on the head that looks like the picture of the sensor on-line.
I have a 2002 f150 4.2 code p0340, ran rough, replaced cam sensor. drove after replacing and it runs fine now, code and service engine light comes on after restarting. from what i have read could this be a wiring problem?
