P0340 Code: Camshaft Position Sensor on Mitsubishi Galant Code P0340

www.johnsadlers...
HI Every: 2002 Mitsubishi Galant 2.4L with code P0340, this video shows you how to replace the Camshaft Position Sensor.
The customers state they crank the engine over and it goes vroom vroom vroom vroom vroom, and it doesn’t start.
Sometimes it’ll start right up.
Check engine light came on.
We have a code PO340 camshaft position sensor.
And now I’ll show you how to replace it on this engine.
The sensor is located right here on the back of the cylinder head, just like on a … you would have a distributor on a earlier model vehicle.
And this is the sensor right here. And I’ve already taken a little bit of brake cleaner and cleaned up this area around here.
And I’ll show you, we just take a little bit, just a couple little spots that I missed, but we’re just gonna kinda clean around there, because this goes right in the cylinder head and there’s oil in there.
We don’t want to have any dirt or debris go inside there.
So we’ll take a little bit of air and blow it off.

Great video, im not mechanic but you serm to have nailed my problem and simplified it dramatically

[@anthonybeckman4584]

Life saver you guys! Thanks for the video.

[@JohnSadlersAutoRepair]

Your welcome Anthony!

[@lightintheart]

I cannot THANK YOU ENOUGH. Your video was SO HELPFUL that I was able to do this on my own representing all the FEMALES out there doin' it DIY style tryin to save that money! I literally said to myself out loud as I was embarking on all the loosening of the nuts, "Thank you handsome mechanic guy for making that video" and everything went smoothly. I even did it with a flashlight on at 7:30pm (not a smart idea but that's how well it went). Thank you again John! *SUBCRIBED*

[@JohnSadlersAutoRepair]

Wow! That's really Great! Your very welcome!!!

[@M41409K]

I have a 2003 Galant ... is camshaft or crankshaft the same thing??

[@JohnSadlersAutoRepair]

No, the crankshaft sensor is down close to the crankshaft at the bottom of the engine, the camshaft is at the top like in my video.

[@M41409K]

John Sadler's Auto Repair in my situation the car turns off when driving also the rpm will suddenly will go low and high to the point were it shuts down and I would have to wait for it to be able to turn it on.

[@JohnSadlersAutoRepair]

M41409K sounds like it has several problems. need to have a scan tool hooked up to it and watch the readings when the issue happens

[@LayZeeDawg]

Thanks for the video, wish the crank sensor was this easy to change.

[@jewelsib]

Great instructions even me a women not knowing how to do much more than adding oil and water was able to do it by following you video but you should really add video for taking off the air filter housing because there is not a video out there to follow and had to find someone to show me But now I have my code cleared and all is fixed Thank you

[@JohnSadlersAutoRepair]

Your welcome, next time I do one I will include removing the air filter housing.

[@joserosas5420]

Very nice and well put together video. Even someone with minimal automotive skills can follow along to replace it. Thank you so much for sharing. 👏👍

Your very welcome!!!

[@Jeffdrarmy]

Great video sir! I did mine today and it worked! I didn’t plug the new one in and the car didn’t start, removed the air box hose and plugged it in and it ran like a charm!

[@JohnSadlersAutoRepair]

Thanks Jeff! Glad I could help.

I have a 2020 Mitsubishi mirage G4 I need to replace my camshaft position sensor in it I don't know where it's at, I sure appreciate if you can help me find it so I can replace it.

[@angelf9800]

I had the same problem I had code po340 and I replaced it with a aftermarket one and didn’t work still have code po340 what can it be or do I have to buy the original part

[@RHD_Civic]

Currently going through the same with a 2012 did you ever figure out the problem?

[@paranorml]

Could you please let me know wheres its located in a 2000 MIRAGE 1.5L... CANT find any info on it.🙏🏼

[@JohnSadlersAutoRepair]

Camshaft Position (CMP) Sensor is in the distributor.

[@paranorml]

@@JohnSadlersAutoRepair thanks, so its built in?. Not a separate part. I could not find it anywhere.

[@dh2236]

I have this code on my 2001 3.0L V6 Galant. Any idea where the Camshaft sensor is? I looked at the service manual and it doesn't seem to have one.

Ok Idk if anyone is listening out there but here goes, so one night it was raining really hard, I parked my car, and got out, got back in 10 minutes later and the car wouldn’t crank, wouldn’t start, I tried to jump it nothing, got my car towed home. I replace the crank and cam shaft sensors, replaced the battery, the starter, the fuel pump, and all the fuses....after this, car now cranks, but that’s it, it just cranks, if I do it long light smoke comes from the engine bay, I mean really light smoke, if u were looking hard u wouldn’t even see it....I am stumped on what the problem could be, I’ve invested a lot of money into this car, and I’d really like to get it running again, it’s 80% modded, full body kit, after I get it running again I’m gonna throw on the fender flares, side skirts and get it wrapped, I swapped the hood for a carbon fiber with air vents it was $1200 the body kit was $700, I’ve put on new headers, ignition coils, please if anyone could help...Mitsubishi eclipse spyder gs 2004

[@LuisRomero-eq6yf]

Maybe water got in your gas tank, something similar happened to me car wouldn’t start only cranks I ended up blowing a seal

[@PhilWithSuper]

Hey, so I replaced my sensor with a new one since I had a random missfire and was getting the P2034 code. Once I replaced it with the new sensor the car refused to start. I then put the old sensor back in, and it will run, but now has a rough idle. It feels like the timing has retarded quite a bit. Would you know why the new sensor would cause the car not to start?

[@MrDellion214]

Did you find out what was wrong? Mines did the same thing

[@PhilWithSuper]

@@MrDellion214 Unfortunately not really. I brought it into our family mechanic and asked if he could take a look, and he got his own sensor to put in and he said it worked just fine when he did it. So my best guess is that it's just a faulty sensor

[@scorpiontube712]

Hey i need your help here. My 2004 Lancer Sportback 2.4 suddenly stop while im driving i connect the ODM and it show PO340 I change that sensor and still not starting but it gives crank. What should i do next? Thanks!

[@JohnSadlersAutoRepair]

I would check the timing belt and compression next.

I have a 98 galant carburetor engine (4g93). The issues are: crank no start(backfires sometime, I'm thinking, "bad timing, poor air fuel mixture) , blinking neutral light once the shifter goes into Drive and the rpm is mad low.( no issues in reverse)... any help would be very much appreciated! Thanks

[@JohnSadlersAutoRepair]

Hi Wesley, I would remove the distributor cap first and look for cracks inside it. The remove the upper timing belt cover to inspect the belt condition. Sometimes they will jump one tooth and run poorly the way your describing.

[@wesleyreid3128]

[@OnlineCitizenTV]

Hi John, great work. I have a Galant 2001 2.4L exact same code on diag test and followed you and replaced the sensor. Now I still get no engine start and yet cranking :/ I only forgot to detach battery when starting. What would be your guess?

[@JohnSadlersAutoRepair]

My apologies for the late reply, did you get the car started yet? Where did you buy your sensor? Not disconnecting the battery shouldn't make any difference.

Great video. I followed instructions. Took it for a drive. Codes were cleared. The next day code came back. I unplugged it. Hooked it back up. Code went away. If it happens again should I replace the wire harness? 2003 galant 2.4l

[@nicolasreiss7738]

Also. Kt would originally start. But would not restart after it warmed up. After replacing it would start fine. But cut out while driving.

[@JohnSadlersAutoRepair]

Check the inside of the connector, sometimes a female tabs get pushed too far apart and sometimes oil gets inside there also. You can take like a little ice pick or something and push those tab closer together and spray some electrical contact cleaner inside and blow it out with some computer air

[@nicolasreiss7738]

[@thatcutndude1]

There is another sensor below that cam sensor..I thought that was the sensor can you tell me what that is they look almost identical....I changed mine...but I'm still not getting power to my fuel pump...I'm thinking crank shaft sensor need to be changed....po 340... Is the code I got but have spark now but no fuel

[@JohnSadlersAutoRepair]

What is the year and model of your vehicle?

[@JohnSadlersAutoRepair]

So if you spray a little carburetor cleaner in the throttle body the engine will start?

[@thatcutndude1]

Yes it will start... 02 Mitsubishi eclipse 2.4l... I also took the fuel pump out and put a battery to it and it worked... I put the fuel pump back in car with a battery to it started the car and it ran as well...but when I plug the harness back up nothing ..I don't hear the pump prime or nothing at all...im thinking the fuel pump relay or the mfi relay that shuts the fuel pump down..I'm trying everything... sometimes it starts sometimes it don't...but never when driving already....thanks for replying back...I just purchased the manual so hopefully I'll find something soon...

[@thatcutndude1]

Well here's wat I did to get her up and running...I wasn't getting power to my fuel pump...and I confirmed the pump works...so wat I did was straight wired my hot and ground wire from the pump to my cigarette lighter in the back...it gets power when the car is on...it works like new again...but I still want to find out wat did I bypass to cut the fuel pump...and it wasn't the fuel pump relay.... computer need resetting I'm guessing...and also..I changed my tail lights...to LED's now my cruise control don't work...hey...I'm good...I like my tail lights...thanks for your help

Does your engine run? Is your timing belt is one or two teeth off and either won't run at all or or can set codes and run poorly

John Sadler's Auto Repair yes it runs good I check the timing like 3 times all marks match the balancer thing is in the right position, wonder if a weak starter may trigger those codes,
