Ford - Explorer :: 2002 4.6L - Dreaded P0340 Code
Apr 13, 2012
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...

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.

My 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.

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).

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?

The p0340 code is the cam position right? Ready says bank 1.. Is there 2? Where the bank one is? And do I need to get on tdc on cyl one first or not?

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....

The vehicle has 160,000 miles and had been running great. I pulled into traffic, put the petal to the floor, and it started stumbling and shaking. I pulled into the parking lot where I was going and expected it to die but it maintained idle but shaking real good. When I started it back up the SES light came on. I was able to coax it home but there was no acceleration, wouldn't go over 40 mph, and was still shaking bad.
I used my code reader and got the code P0340, camshaft position sensor. I replaced the sensor but it is still doing the same thing and still showing the code. It will start if I push the gas while cranking but it won't rev over 2K. I am thinking it jumped timing but most of the threads I read say they have never seen this on these engines. I want to get some opinions before I start removing the timing chain cover.

Just got a check engine light last night. Pulled the code and got a P202a fault. Some digging indicates its the Ad-Blue tank heater module. TDI forum indicates its anywhere from $850 to 1K to fix. Also that it's not covered under any extended warranty (now there's a shock!) The cars going back to VW so that's not happening.
Is this one of the conditions that will cause the car to go into limp mode at some point? I know that happens when the ad-blue runs low. I'm in Florida so the heater isn't really a big deal. I need to use it another couple of months and I don't want to have this thing leave me stranded. If I have to I'll park it.

My 02 Explorer (XLT, 4.0) decided to throw a new code today. PO136, O2 Sensor Circuit (Bank 1 Sensor 2).
While it may be a wire issue, I still plan to replace the sensor. So the question is;
Can I get to it from under the vehicle or is there an access panel under the console like on the 2nd gens?
I have the sensor on order and plan to get it done on my days off next week.

A warning came on the display with the words "PS Main" and a picture of a battery. I took it to a dealer and he gave me the bad news: I allegedly need a new hybrid (main) battery. The diagnostic code was P3009--I didn't know about sub-codes, so I didn't ask if there were any. P3009 means that there is an electrical leak from the main battery.

My 4.65L V8 Explorer has an issue in low gear - RPMS rev high but car doesn't shift up.. eventually "catches" with a jerk but the OD Light started flashing and the Systems Screen reads Check Transmission. Light goes out and message goes away after turning car off and restarting. Had one Tech look at it - he said second gear is toast and need full transmission rebuild. Another Ford Tech looked and could just be solenoid needing replacement and advised to have a transmission service (not a flush) done....

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?

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.

I 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???

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.
