Ford Aerostar :: Code PO340 - Break In Camshaft Sensor Circuit
Feb 13, 2006
I am having a problem repairing my 1997 aerostar with a 3.0 engine. Code PO340 comes up. Ive replaced the cam sensor, cam sensor housing and the pcm. Using the diagnostic charts, I've thoroughly checked out the wiring, in the harness, at the sensor, and at the pcm. I've set the cam sensor housing at TDC with the appropriate timing tool. Code P0340 still comes up. I've seen a couple of other aerostars with the same problem. Ford TSBs .....

I have a 2007 ES350 with 90k miles. Purchased in August. I had ignition coil go out and decided to change them all and the spark plugs. When changing cylinder 5's coil and plug, I tried to push the wiring harness out of the way to remove the coil. Result, I moved the wiring harness too far and disconnected the 3 wires (black, yellow and red) that were connected to the cam position sensor connector. (I should've just removed the sensor SMH) I disassembled the connector, got it down the internal pins, soldered the pins to the wires, placed the pins back in the connector and reassembled it with the wires in the order that they appeared to originally be.
Plugged it back in and put everything back in place. Started the car and code P0352 was cleared but replaced with code P0365 Camshaft Position Sensor B - Bank 1 Circuit Malfunction. I'm thinking, either I put that pins back in the wrong order or one of the wires isn't properly soldered in. Either way, I ordered another connector and it should be here tomorrow. I need Either a wiring diagram or a picture of the camshaft position sensor closest to cylinder 5 connected with the wires in the proper order .

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.

So, I've got a new toy (FORscan ODBII software) and a new code that isn't turning on the CEL (yet) but also didn't show up in OBDWiz either.
P1100 - Mass Air Flow (MAF) Sensor Circuit Intermittent
I cleared it, drove a few miles, checked again and it's set again.
The little troubleshooting advise window in FORscan says to monitor the MAF voltage while wiggling the MAF harness and see if the voltage goes below 0.23v or above 4.60v. I was unable to manually make that occur, no matter how I tapped on the MAF or wiggled the wiring.
However, in oscilloscope mode, look at this (at idle):
It sure looks like it went below 0.23v here. I have no time tonight to do any research. This is a relatively new MAF (one week old, Delphi unit). I think I'll swap it out for one of my two old OEM MAFs sometime this week. But if any opinion about this, pipe up. I do damned little work with scanners these days, and the tech keeps changing.

My 1.5L 2000 Hyundai accent is reading p0342 code.(cmp sensor circuit low Input). I have changed out the sensor from a parts car and it's still reading this code. I've read it could be timing or an issue with the starter wiring.

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.

While driving home my cel came on, the next morning I took it to the dealership. The code read camshaft sensor. The mechanic ask how the van was driving, I said perfect, no issues no nothing. He said that was kind of surprising.
The next morning went out and no cel at all and van still running fine. Spoke with another mechanic who said a number of things can cause that code and to hold off on the new sensor and see what happens over the next few weeks engine performance wise and if CEL comes back on.
What should I do? Car is a 2002 KIA Sedona mini van that has had zero engine issues while I have owned it since 2010.

So my little car.....driving home from jersey (about an hour and a half) and within the last 2 miles I notice the car just shut off. Not any electronics just the motor. Pulled over and tried to start it an it just cranks prolly no fuel or spark. happened to have my obdII scanner with me. It says camshaft position sensor(po342). Only code in there. Sounds simple enough. Got a new one and put it in. Just cranks. Plugs and wires were done about 3 months ago and I drive about 40 miles a day 5 days a week. I did the timing belt last spring so I opened that back up to make sure the timing hadn't jumped for some stupid reason. It's perfect. Noticed now after doing all of that there is some (a little) oil in the throttle body. I know about blow by and don't think I should have that much at 113k but who knows.

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 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?

My daughter spun her timing belt on her 1.5L accent. when she did, she bent the valve rods and all were replaced. The original code that was thrown was the one in the title. Ordered a new camshaft positioning sensor for the car. Looks a little different than factory. He installed it, and car is still pulling code. He accidentally threw away the original before confirmed that the problem was solved. Why the code is still pulling?? I can tell you this, I can clear the code, start the car and drive without code coming back on. As soon as I shut the vehicle off and restart, engine light comes on. Car runs fine. Had a complete valve job, new timing belt and water pump installed.

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.

The computer is returning P1379 camshaft position sensor. Where is this sensor located on a 2002 Toyota Camry 2.4L and how easy would you rate the job of replacing it?

She is a 1999.5 Golf 2.0 (although, she just has a rabbit symbol on the hatch, is she a Rabbit or did someone remove the Golf badge?) I just bought the car, with less than 160,000 miles. The dome lights work sometimes, Door Ding works intermittently as well, but sometimes will "glitch" in other words it will be making the sound but it kind of stutters? Odd? The horn sometimes works, however it is very silent? Check engine light is on with a camshaft position sensor code and miss on cylinder 3. Someone told me to replace the "109 relay"... could this be the problem or is this the CCM?

I have a 2004 MK4 Golf 2.0l that's been throwing a CPS error code. My brother was going to come down to visit for a weekend. He had done some diagnostic work and had me order a timing kit and a camshaft position sensor from ECS.
So, with my assembled parts, I brought the car in to a reputable shop. Anyway, the guy does the work and now the car is ready and saying that the CPS took nearly 4 hours more of work.

2007 Lexus ES350 with 177k miles. Getting a P0368 (Camshaft Position Sensor B Circuit High Bank 1) Error. I can't seem to find online where this sensor is located at.

I have a 2007 Camry V6. Last weekend, I changed all the spark plugs and five ignition coils. (117,000 miles on car). In January, I replaced the #6 ignition coil. Last week i threw a code for the #2 coil. Fearing the domino affect, I replaced all five remaining coils and changed all 6 spark plugs while i was in there.
Now I am throwing code P0368. This happened immediately after i changed the coils and plugs. What is this about!?!?!? Ive driven it maybe 40 miles since the plug/coil change...engine light is on the whole time. Is this sensor bad or does my car need time to "rethink" with all these new parts ...

Check engine light is on, this is the code that came up when checked at OReillys, "P0113 Intake Air temperature sensor 1 Circuit high input". Earlier took it to repair shop, he did not give the code, some sensor needs to be changed (don't know if he came up with same code). He had erased the code but it came back on within minutes. Wanted to check if there is any cheaper way to fix this. This is a windstar van.

2004 Sport Trac V6. Been having hard shifting and P0715: Input/Turbine Speed Sensor Circuit. Cleared the codes and still returns.
From my searches, readings and looking at the parts diagram. On the newer 5 speeds the sensor is the one on the inside of the tranny. This requires taking the entire tranny apart? Is there an external connector for the sensor that I can check or clean first? Replace this sensor. I know the older ones were mounted on top of the tranny. I think this one is mounted on the inside though.

I have a 1997 Toyota Tacoma 3.4L ... After having some problems a week ago with the truck dieing at every stop sign or any time my foot wasn't on the gas. Eventually the truck would not start at all. I finally got a CEL that gave me P3040 (Camshaft Position Sensor Circuit Malfunction) So I changed out the sensor and the truck fired right up and ran for 3 days.. Now the truck does not start again and I am getting the same CEL code.
