2002 Mitsubishi Galant 2.4 with repeating error codes P0335,P0340

This video may help ... the sensor is underneath the timing belt cover so it is a bit involved to get to ....

Here's a link on your code Jay. P0170 Fuel Trim Malfunction Bank 1 Here's a link on code P0340. https://www.obd-codes.com/p0340 Here's a link for code P0335. https://www.obd-codes.com/p0335

Look more closely at the 1 and 4 coil, also, check for trigger signal to these coils. I mostly suspect the trigger unit.

i have a 2000 eclipse and got a trouble shooting code p0340 for a camshaft position sensor. but my car dont have one?

some vehicles set these codes when ignition is turned on but engine not running,
but then goto a not pressent code(history code) or no code present, when engine is running. This may be the way the system works, which with genuine scanner it may
show this but with some aftermarket scanners may only show that the code sets,
not what its status is or if its gone, it remains displayed.
So you could clear codes, engine not running, cycle ignition and if code comes back again without starting engine this is normal for this system (NO FAULT).
If it only sets again when engine has run,
is cam timming correct?
teeth on reluctor wheel all o.k. bent or dammaged?
or debris stuck to reluctor wheel?
Earth circuit could be shared with both sensors is it ok? -repair wiring or bad earth.
low Ohms reading test from sensor connector.
Is power to sensor circuit uninterupted & ok? -repair wiring

Autozone will read the code and give you a print out of the definition for free.

Or you can google p0340 maybe add galant and you will find out what is is.... (camshaft position sensor)

Hi, here's the solution: P0335

Your P0340 is a different problem from your P0303, but they may be related.

Since the code P0340 indicates that there is something wrong with your cam speed sensor, your misfiring in cyl3 may be caused by this.

This points to addressing the P0340 error before the P0303 since it could be contributing to the 303 in the first place. Look at your cam speed sensor in cyl3 and maybe this would solve both problems at once.

Hope this helps.

Glad I can help. :)

Hi, I found a couple of good articles on those codes. Rather than just copy and paste here are the links:
