Code P0340 Toyota Description
If no pulse signal is transmitted by the camshaft position sensor despite the camshaft rotating, or the rotation of the camshaft and the crankshaft is not synchronized, the ECM interprets this as a malfunction of the sensor. Also, when the sensor output voltage remains at below 0.3 V, or higher than 4.7 V for more than 4 seconds, the ECM stores a Diagnostic Trouble Code (DTC).
What are the Possible Causes of the DTC P0340 Toyota?
- Faulty Camshaft Position Sensor (For Intake Camshaft)
- Camshaft Position Sensor harness is open or shorted
- Camshaft Position Sensor circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P0340 Toyota code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Discuss the causes and fixes for P0340 Toyota OBDII Code

Why!! It's great that the so called experts give a description of faults caused by the cam position sensor itself. But no where does it address the reason for having a cam shaft position sensor in the first place which is basically to make sure the #1 TDC is not out of alignment with the camshaft. In my case the timing belt jumped a few teeth and gave a p034 fault code. In my case the difference of one tooth out on the timing belt was a difference of going from 38 mpg to 32 mpg.
-
Thank you! will add that to the possible causes. That's the comment section of AutoCodes.com is all about. Not all the vehicles or components fail for the same reason
-
Will I read power from the engine control with the cam position sensor unplugged? What voltage should it be. I Ohmed the wire fron the control to the sensor and it checks good.
-
Could it be the cause of poor acceleration and much reduced mileage especially with AC on my 2000 toyota solara 5SFE? It pulled the P0340 code
-
Yes, the "Camshaft Position Sensor" ( P0340 ), could cause poor acceleration and engine to stall.
-
Seeing as though STM didn't reply I would really like to know the answer to his question. Mine is a 2007 Yaris 1kr-fe. Got the P0340 but sensor has been replaced and I am measuring 5v between the two outer pins and I am also getting 5v on the Centre signal pin. Please let me know if this is right. Thanks
-
I also test the cable from the sensor side to the ecm side for continuity to make sure it was the right cable and I get positive 5v on sensor side and negative 7v on ecm side
-
The best way to check the the Camshaft Position Sensor function is with an oscilloscope. You wont be able to get a good read with a volt meter, but I have attached an image of the test you can do with an ohm meter.
-
I got the information from the factory service manual, and unfortunately that is the only one got. Even the wire diagram only shows two wires.
-
i have code P0341 (toyota prius 2004), wot i sthe difference between P0341 n P0340, r they 2 different types of sensors?
-
It's the same same sensor. Difference is that the P0340 means that there is a problem with signal (dead sensor or wire) and the P0341 that the signal is low (weak sensor short circuit)

Auto help me with p0340 toyota slenner model 1998 the is doing high starting in the morning sometime is doing it afternoon time to time is doing high starting and what can I do to fix it and help me locate the camshaft position sensor bank 1
-
Unfortunately I don't have the service manual for that model. You probably have to replace the camshaft position sensor.
-
I hv toyota camry 1996 model is remove black smoke and I scan the car I hv p0340 nd p0110 what can I do to fix the problem
-
You have 4 or 6 cylinder engine?
If you have the P0340 code, then you have to replace the Camshaft Position Sensor.
-
Where is the Camshaft Sensor located on a 2000 Toyota Sienna???
Thank you -
Where is the camshaft sensor located on the 4.7 (2006 4Runner sport). I can't find where it is and/or how to get to it.
-
The sensor is in front of the engine, but you have to remove the timing belt cover to access the sensor.

i was lead to believe the camshaft position sensor was in the distributor so i replace it still getting code so now i have the crankshaft position sensor and i hope this work and also a new alternator cause now thats went out.. 96 camry
-
Do you have 4 or 6 cylinder engine? if the code is for the Camshaft Position Sensor, why are you replacing the Crankshaft Position Sensor?
-
Camshaft position sensor is located behind driver's side upper timing belt cover, near camshaft sprocket with electrical connector near front of driver's side upper timing belt cover.

1999 rav4 timing belt snapped while stopped at a red light, I replaced the belt and engine wouldn’t start at first, had to replace both camshaft and crankshaft sensors. They were both covered in oil and debris and static/magnetic components were dented/damaged. After everything I recharged the battery and finally got it to start up properly but not it’s running really rough and it can’t be the oil cause I just did and oil change a week or 2 before the timing belt snapped (less than 500 miles). I’m 98% positive I got the timing belt on properly but not sure if it’s too tight or not tight enough. Also I was checking the spark plugs while the engine was running by pulling the wire off of each plug individually and there was only one plug that didn’t make a difference in the way the engine ran (the third plug from left to right, 4 in total). My question, is it possible that the spark plug is not good and could be causing the ECU to keep showing that trouble code? There’s no other codes showing but p0340 while driving braking or idiling
-
I never seen a bad spark plug triggering the P0340 code. Either the timing is off or the new sensor you got is bad. Did you change the timing belt tensioner with the timing belt?
-
Can you please help me locate where the Bank A and Bank B cam shaft position sensors on a 2013 toyota venza 4 cyc. LE? Thanks for any and all help.

You vehicle has only 1 bank (Bank 'A'). For your model year, the P0340 code is for the Camshaft Position Sensor (For the Intake Side)
