I have a 02 cheve venture and i have a code in it so i scan what maybe causing it so it show that 2 codes it was PO341 crankposition sensor A, CRK Range/perf camshaft position sensor A....I make some action i check the coil for resistance which i come up to 5.76 first coil sencond coil was 5.62 and the third one is 5.77 so im guessing that the second coil was bad so i change it but the problem is still the same so i guess its not working anways the new coil was 8.2 ohms i was thinking dat all of my coil was already bad too because they way too low..it gonna help me a lot if someone make some comment on my proble i appreciate a lot God bless

codes p 0014, 0340, 0341, 0345, 0346 all refer to the cam shaft position sensor==causes include-- advance mechanism faulty - CMP sensor --insecure cam rotor --wiring short to ground --air gap--ECM
codes p 0420, 0431 refer to the cat converter=== causes --cat converter failed ---wiring --- HO2S ( heated oxygen sensor)
code p 171 is a faulty HO2S sensor and
p 174 refers to system too lean bank 2===causes --intake /exhaust leak---fuel pressure /pump---injectorr/s AIR system---hose connection/s
Diagnostic Trouble Code (DTC) P0341 has a generic description of "VTC phase gap".
"VTC" stands for Variable Timing Control. Basically, what the computer is trying to tell you is that it is having problems controlling the variable cam timing in your engine. There are MANY possible causes for this. The MOST COMMON cause is the engine oil level being low or the incorrect viscosity of engine oil being used. also, failure to change the oil at regular intervals can cause deposits that can cause your cam actuator to stick or bind, or your VTC solenoid to stick. Another possible cause is a worn/loose timing chain.
No I can not give you the code number because I did not scan it for you. The Diagnostic Trouble Code will show ( example 02 Sensor Bank 1 sensor 2 ) for the sensor at fault, or something simaller for one of the other 02 sensors. Fore ( example 02 Sensor Bank 2 Sensor 2 ).The parts store that did the scan for you should have given you the particular fault code as well as its location. If you replace one 02 sensor, you should replace all of them. Good Luck and have a good XMASS.
MOST OF THE TIME AN 02 CODE DOES NOT MEAN REPLACE 02 SENSOR..SOME AUTO PARTS STORES WILL SCAN YOUR CAR..TELL YOU CODE 02 SO PEOPLE AUTOMATICALLY REPLACE SENSORS...IF YOU CLEAR THE CODES DOES THE CHECK ENGINE LIGHT COME BACK ON RIGHT AWAY OR DOES IT TAKE A LITTLE TIME... IF IT TAKES A LITTLE TIME THEN YOU HAVE SOME PROBLEMS THAT ARE CAUSING THE EMMISSIONS TO BE OUT OF RANGE.. IF THE LIGHT COMES BACK ON RIGHT AWAY YOU HAVE A PROBLEM IN WIRING HARNESS BETWEEN THE SENSOR AND ECM....MAIN COMPUTER.....OR SECONDLY POSSIBLE PROB IN THE MAIN COMPUTER...GET SOME OF THOSE ANSWERS AND FIND THE EXACT CODE THAT RETURNS THEN GET BACK WITH ME FOR MORE HELP
