How to tell if a camshaft position sensor is bad?

Purchased a 04 rio with a blown timing belt. I put a new head on the car, timing belt etc. triple checked my marks, spun the enginge by hand before starting, check marks again. then started the car, which fired right up and runs smooth. But I have a camshaft position sensor code. P0340. I clear the code then restart the car and the code dont return until I shut the car off and restart. any ideas? I also unpluged the camshaft position sensor while the car was running and it did nothing.

Check the pins in the cam sensor,one might be bent and not making a good connection.I am assuming you did not have a cam sensor code before unplugging the sensor.

SOURCE: 2002 kia rio rxv check engine light came on again..

On my wife's car the mechanic said it was gas cap. (NOT!!) I cleared with an OBD reader and the code suggested a leak in the evatorator system. I found a steel tube that was routed over the weld flange of the gas tank. It went from the front of the car, down the drivers side, over the weld joing of the gas tank and into a charcoal evaporator filter on the passengers side near the rear wheel. The tube crossing over the gas tank crumbled when I touched it. I replaced it with a short piece of reinforced neoprene hose (to cross over the gas tank) and a couple of hose clamps. Cost of parts was about $5.00. Havn't seen Check Engine since. Good luck

No repair should only last three weeks...don't touch anything and have the shop that did the work come and get it. I have lots of ideas but it will need to be checked over to verify them. Rather than comment on the "maybe" of this, have them check it out. Any reputable shop will be more than willing to do what's needed...Bad jobs ruin that reputation!

Start with the simple and replace the fuel filter. The fuel filter should be replaced every 15,000 miles or once a year to ensure the fuel system is running 100%. Auto Zone will have the fuel filter and can give you the step by step instructions to getting the job done with common tools. If it's the fuel pump failure, you have not gotten the car restarted. Good luck and keep me posted, be glad to know you got your car running 100% again soon and please rate.

evap purge valve fault is your p0443
p1693 is manu. controlled aux input output fault
p1693 is a code for an open or short to ground for the check engine light
does it light up when key is on? if so then it is a left over code from some previous repair attemt
the evap code wont prevent starting
check for broken timing belt
check for fuel in tank and that it has proper fuel pressure

Peugeot 3008 camshaft sensor location

The camshaft position sensor on a Peugeot 3008 can be located in different positions depending on the engine model and year of manufacture. Here are the possible locations:
  1. On the engine cylinder head: In some Peugeot 3008 models, the camshaft position sensor is mounted on the engine cylinder head, near the camshaft.
  2. Near the timing belt cover: In some other models, the camshaft position sensor is located near the timing belt cover. It can be either on the engine block or on the cylinder head.
  3. Behind the camshaft pulley: In some Peugeot 3008 models, the camshaft position sensor is located behind the camshaft pulley.
To locate the camshaft position sensor on your specific Peugeot 3008 model, you should consult your owner's manual or a repair manual for your vehicle. Alternatively, you can seek the assistance of a professional mechanic or a Peugeot dealer.

Kia rio not starting

Timing belt should have been changed at 60,000 miles. A loose timing belt or teeth missing from synchronous belt will lose timing. Damage to valves can occur if timing is not correct.

04 buick ranier rough idle almost stalls

DTC P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.

Symptoms of a P0016 will or may include:
Malfunction Indicator Lamp (MIL) illumination
The engine may run but with reduced performance
The engine may crank but not start
The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
The engine may start and run, but poorly

Causes may include:
Timing chain stretched, or timing belt skipped a tooth due to wear
Misalignment of timing belt/chain
Tone ring on crankshaft slipped/broken
Tone ring on camshaft slipped/broken
Bad crank sensor
Bad cam sensor
Damaged wiring to crank/cam sensor
Timing belt/chain tensioner damaged

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Camshaft position sensor

The camshaft position sensor is on the rear cylinder head on the left end (the serpentine belt end of the engine - passenger side). It is a son-of-a gun to get at. When it is bad or the connector is intermittant or bad, the symptom will be irregular idle from 500 to 750 RPM or so.
