P0340 Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. Any time the check engine light comes on, a code scanner is needed to interrogate the computer and access the codes for the problem. This information is used by the Engine Control Module to control ignition and fuel injection. I've checked the fuses, they where good. I can barely step on the gas pedal when it is warm and it will start right up.
Remove the nut and 3 bolts and pull straight out carefully, the crank shaft sensor is in the block and may brake off, try not to brake the sensor off. This goes on until the car warms up then it runs fine. Turn the key on, the voltmeter should read approx 10 volts. Vehicle does not drive like it used to If your vehicle , , has , stumbles frequently, has , or , these are all signs your camshaft position sensor could be failing. The sensor is attached by two bolts onto the timing cover.
It does this through the use of a trigger wheel composed of a series of raised points, similar to a star shape, but with a multitude of different shapes in place of the tips of the star. Install the tire assembly and lower the vehicle. I then pressurized the system, ran the air out etc. This can happen while the vehicle is parked, or while you are driving. If you have any of these symptoms, it could mean the needs to be replaced by a professional mechanic as soon as possible. I've got a 94 Grand-Am with a 3100 motor and a 4T60e trans.
I have been having problems with the Temperature gauge working when it wants to. To use the scanner, simply plug it into the connector under the driver's side dash panel. Also notable the upper rad hose had blown and was replaced, and I know the thermostat isn't faulty because when the car reached operating temp the upper rad hose compressed and I assume that means the block sucked it in. It acts much like a switch turning on and off. Anonymous said: I have a 95 Chevy Lumina 3. You think it could be the gauge it's self? Plug locations on4 cyl 1 and theV6 2 Connect the positive lead of the voltmeter to the probe and the negative to a good engine ground. I cleaned it out what I could but did not help.
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. To replace it,I think you need to remove the balancer. This problem should not be ignored because eventually the engine will stop working entirely. The halleffect sensor is located behind the harmonic balancer and lower pulley. Even if you didn't mess with it, re-seat every major multi-connectors you can find.
The wires are not frayed or broken. Any ideas what may be causing this? If the check engine light is on, get the code scanned to see what might be causing the trouble. Remove the camshaft position sensor bolt. Two days ago,my car starting stalling,rough riding,sporting black exhaust fumes. Unfasten the retaining bolt, then remove the sensor from the camshaft housing. The thermostat has been changed twice in the last month, the sensor as well. Install the camshaft position sensor bolt.
You Could check the physical integrity of your wires. The changing gap causes the magnetic field near the sensor to change. Ive had some good battles with it, but it seems to always win. You can see the sensor from the top side, with a 2 point wire connector on it. As the raised point passes the sensor, the pulse subsides. Lightly pry out the sensor being careful not to break it.
Clean out the hole and install the new sensor put a little oil on the new sensors o-ring to help installation. If it seems like it running rough, you may have switched push rod positions by accident, that will cause the car to die out or run rough. Without this information, the engine would not be able to function properly. When that happens, the new starter cranks very well but the engine won't star … t until it is determined what happened and the connector is plugged back on. Once this is done, turn the ignition key on with the engine off. If you , it can lead to serious engine problems, such as the engine failing. Overlooking repairs and ignoring warning signs of wear and tear to the point where they start affecting the stability of the neighboring components or the entire vehicle itself only complicates the repair procedure.
Attach the sensor harness connector. Remove the coolant recovery reservoir. Does any body has any idea what can cause this issue? Then it starts to function very normal and acceleration is good. Remove the right hand tire assembly. Disconnect the negative battery cable. Most orders are shipped the same day.
There are a few warning signs to watch out for before your camshaft position sensor completely fails and shuts down the engine, making. It is a 3-wire sensor with one purple, one light green and one light blue with a black stripe wire. It is about the size of two sticks of gum. I've just eliminated the leaks that the car once had by replacing the lower intake gasket. The sensor in the Grand Prix is a 3-inch cylindrical sensor located on the side of the engine facing the firewall, directly under the exhaust manifold. I'm going 2 run a vacuum pressure test on it and c if that could b it prob.
