There may be more than one issue. Here's some possibilities:
1. The new sensor you bought is defective. I have run across this problem a few times. Most notably was a mass air sensor for a Maxima that the first 3 NEW sensors were defective right out of the box.
2.Look for oil in the sensors plug socket and the pigtail connector. If oil is present, spray out both the socket and pigtail with brake cleaner. (Be sure to wear safety glasses when doing this)
3. The timing belt tensioner is losing/has lost the ability to keep tension on the timing belt and it's out of time.
4. There's a break or a sort in the wiring. You'll need a schematic and a mutlmeter to check for continuity.
(Least likely) 5. The computer is failing or has failed.

SOURCE: replace oxygen sensor

REMOVAL & INSTALLATION Start the engine and allow it to reach normal operating temperature, then turn the ignition switch OFF. Disconnect the negative battery cable. Open the hood and locate the O2sensor connector. It may be necessary to raise and safely support the vehicle for access to the sensor and its connector. NOTE: On a few models, it may be necessary to remove the passenger seat and lift the carpeting in order to access the connector for a downstream O2sensor. Disengage the O2sensor pigtail connector from the vehicle harness connector. NOTE: There are generally 2 methods used to mount an O2sensor in the exhaust system. Either the O2sensor is threaded directly into the exhaust component (screw-in type) or the O2sensor is retained by a flange and 2 nuts or bolts (flange type). WARNING To prevent damaging a screw-in type O2sensor, if excessive force is needed to remove the sensor lubricate it with penetrating oil prior to removal. Also, be sure to protect the tip of the sensor; O2sensor tips are very sensitive and may be easily damaged if allowed to strike or come in contact with other objects. Remove the sensor, as follows: Screw-in type sensors: Since O2sensors are usually designed with a permanently-attached wiring pigtail, it may be necessary to use a socket or wrench that is designed specifically for this purpose. Before purchasing such a socket, be sure that you can't save some money by using a box end wrench for sensor removal. Flange type sensors: Loosen the hold-down nuts or bolts and pull the sensor out of the exhaust component. Be sure to remove and discard the old sensor gasket, if equipped. You will need a new gasket for installation. Perform a visual inspection of the sensor. Black sooty deposits may indicate a rich air/fuel mixture, brown deposits may indicate an oil consumption problem, and white gritty deposits may indicate an internal coolant leak. All of these conditions can destroy a new sensor if not corrected before installation. To install: Install the sensor, as follows: NOTE: A special anti-seize compound is used on most screw-in type O2sensor threads, and is designed to ease O2sensor removal. New sensors usually have the compound already applied to the threads. However, if installing the old O2sensor or the new sensor did not come with compound, apply a thin coating of electrically conductive anti-seize compound to the sensor threads. WARNING Be sure to prevent any of the anti-seize compound from coming in contact with the O2sensor tip. Also, take precautions to protect the sensor tip from physical damage during installation. Screw-in type sensors: Install the sensor in the mounting boss, then tighten it securely. Flange type sensors: Position a new sensor gasket on the exhaust component and insert the sensor. Tighten the hold-down fasteners securely and evenly. Reattach the sensor pigtail connector to the vehicle harness connector. Lower the vehicle. Connect the negative battery cable. Start the engine and ensure no Diagnostic Trouble Codes (DTC's) are set. Posting pictures next......

SOURCE: p0051 code, where is the sensor located, where is

Bank 2 is passenger side, sensor 1 is the one up closest to the exhaust manifold. Plug in type (just remove old and plug back into the wiring harness connector) is about $90 at Autozone. You can get a cheaper one that you splice but it's confusing to understand which wires to splice together. Don't forget to buy the special socket, $10, to remove and install the sensor. It's split up the side for the wires. Forget trying to use an open end wrench, socket is best.

check the mass air flow sensor there maybe dirt on the filiment inside the sensor causing false readings. cleaning or replacing it may make the codes go away.

SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

Code 340 is a cranking code for the cam sensor that's not working and the1391, it shows intermittent signal. Check the connections and change sensor, make sure it doesn't touch the cam. If your belt is old you should check it too. Good Luck

04 dodge neon showing P0325 and P0340 codes at same time.


Code 0325 is for a Knock sensor. Code 0340 is for the Cam sensor #1 if this is an engine with 2 heads and it is an indication of a single sensor on single head engines.

So if you do have a multiple hed engine, you may have removed the good sensor and left the bad sensor in the other head.

Remember to wipe the computer memory after installing new parts.

1997 plymouth voyager , It gives the P0340 code I had the cam sensor and crank sensor replaced. It will start sometimes and will not start for a long period other times I have also replaced the Computer...


Because It that code refers to the circut it could be any thing from an open circuit or bad ground, to a PCM if you have replaced the computer be sure that it was properly flashed or the vehicle wont run, most PCM/TCM/ECM aren't plug and play but if you replaced both sensors this is really all thats left its one of the items listed, I would check grounds that is kind of a popular one on the voyager.

Rough idle and misfire on ram truck


Change cam sensor & erase codes.( disconnect battery for a minute or so after.) 340 & 1391 refer to cam sensor problem, and all other 300 codes are cylinder misfires that should disappear when cam sensor fixed.

P0340 code in my Jeep Liberty 2002


Since a P0340 Could be either the Cam Position Sensor or The Crank Position Sensor they are obviously in 2 different spots, however they both either sit on the back of the engine or on the transmission bellhousing. Your Cam Sensor is at the top and your Crank Sensor is near the bottom.

Hope this gives you some direction. Thanks for using FixYa!
