Ford - Explorer :: 2002 4.6L - Dreaded P0340 Code
I 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...
Santa FE SM (2001-06) :: 2002 Shutdown When Driving - Code P0340
So 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.

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).

My mother has a 1999 Camry 4cyl. that has code P0340. She says that she was driving down the road and felt like a misfire, saw the MIL turn on. When she let off the gas, she said the car stalled. It is a crank no start issue now. I was able to pull the code, but really am not familiar with Toyotas in General. I am mechanically inclined but do not have access to media such as All Data or a Service manual. Do this is most likely the sensor itself or more of an ECU issue?
View 10 RepliesSanta FE SM (2001-06) :: Crank No Start And Code P0340
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.
Ford Ranger / B-Series :: 1995 - CEL Came On - P0340 Code - CPS Bad
I am having an engine issue with my 1995 Ranger with a 2.3L. I have been having a P0340 code that kept appearing after several attempts at resetting the PCM. I gave up and took it to a Ford dealer for diagnostics and they called the CPS bad. They changed it, but the CEL light immediately came on with the code still kept coming up. The service rep. showed me the old sensor, it had a spot on the head of it where it looked like something was rubbing it. I'm assuming it's slightly rubbing on the gear it points to, which is the oil pump gear, correct? The truck runs fine, no performance issues whatsoever. Is it possible my oil pump shaft has developed play in it's shaft, causing this?

I was checking my oil the other day and when I removed the cap there was this whitish film stuff and gunk on it.

I 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.

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.

I have the error code P0340 and have changed both camshaft positioner sensors, cleaned the air sensor and throttle body and still the engine stalls. I can accelerate at 40, 50, 60mph and it jerks violently. I tried the "locking it in third" trick but it still jerks. Today I unplugged the left cam sensor and the truck idles @ 400rpms, does not stall, and pretty much drives great! Hook it back up and crank it, within 10-15 seconds it stalls. I plan to check the wiring....

I have a 2002 KIA Sedona with the CEL on. I got the code and would like to clear it but Auto Zone who read the code said they were not permitted to clear it and highly recommend not clearing it. So is it bad to clear it and if not how can I do it myself?
View 19 RepliesKia - Sedona :: 2002 - Engine Sputtered A Bit / CEL Came On And Then Went Off
About a week ago while driving to work my engine sputtered a bit and the CEL came on and then went off. As I drove the sputtering reoccurred when I would accelerate from being stopped but went away when I got to higher speeds. Again the CEL came on. Next day I took it to the dealership who read a P306 code and was told it was an issue with the No. 6 cylinder. After driving a few more miles the sputtering stopped happening. The next day I got in, started the van and no more CEL. That was last Wed, and since then I have done over 150 miles of driving and no sputtering and the CEL has not come back on. Could I have just gotten some bad gas or something that caused the brief sputtering and CEL.
