SOURCE: code 1346 on 2002 toyota sienna

P1346 is the code for:
VVT Sensor /Camshaft Position Sensor Circuit Range/ Performance Problem (Bank 1)
If the code came on just after the timing belt replacement more than likely the sensor was damged in some way during the work. The sensor is located in the same area the mechanic was working in while changeing the timing belt. You should have this checked right away. A faulty cam sensor can also lead to the vehicle not starting.

SOURCE: BMW 325xi; 160k; check engine light on-->next day, wont start!

The check engine light is a warning to let you know something needs your attention to be repaired I would try getting a jump. Could be a bad battery. Lets get the battery charged and tested. Cold weather will stop your car from starting if you have a weak battery. You dont need to tow the car just take the battery to Autozone or Walmart to be charged and tested for cca...cold cranking amps

SOURCE: 1993 Jeep Grand Cherokee 8 cylinder, My "check

A failing crank sensor sometimes won't set a code, but it will not prevent the check engine light from coming on.
I'd test it with an ohmeter both hot and cold just to make sure it's good, but think your problem is likely to be a connection between the ignition switch and the computer or a security system fault (if you have one). I'm not absolutely positive, but I believe that both years on that sensor are interchangable. It is also possible that some time in the past, the engine or flywheel was replaced and required the sensor to be changed along with that repair. If the vehicle was running fine before this problem arose then likely, whatever parts were installed were just fine.
In disconnecting and re-connecting the battery it can cause a small electrical arc that will temporarily "weld" a bad connection back together till vibration or temperature change causes the connection to come apart again. That can happen in the harness connections or even on the computer internal board. Neither are easy to find and you will need to check continuity of any and all power wires going into the computer (grounds too) in order
to locate the problem.
Chilton has good wiring diagrams and I'd definitely be using that manual as a guide. If I can find a decent diagram for your vehicle, I'll send it later, but I'm not sure I have one.
Good luck and be patient!

Audi a4 2.0 lt 2006 engine cranks but wont start . started this morning no problem . half an hour later no start . no warning lights on dash


The first thing that you must do here is to have the systems computer checked for fault codes, it should have a few in memory. the codes are read through the diagnostic port under the dash.

Diesel. Reduce power lite turned on. Shut off engine and started back up - lite is off. Can it be driven?


Jerry, Drive to a good shop. So many things can cause reduced power light unfortunately. The first step would be to get the truck hooked up to a scanner/computer and have the computer scanned for trouble codes. One thing that you could try is to drain the water from the water separator that is mounted on the frame under drivers front door. If the PCM picks up on water, power is reduced until water is removed/drained. It could be an exhaust sensor that is reading faulty. Unfortunately from here its impossible to tell you exactly what the fault is because there are just so many engine sensor inputs that could cause your problem. Check the attached links, forums,instruction and guides, Good luck

CRANKING NOT STARTING


Sounds like either the fuel filter or the catalytic converter. You will need to check the back pressure of the exahust and the fuel pressure after it fails. This I say because you did not mention any trouble codes.(check engine light on or flashing)

Check engine light comes "on"


OK, If I understand your question correctly, Your Check Engine light is coming on and you are getting a Diagnostic Trouble Code (DTC) P0240 and we are talking about a 2000 Honda Civic DX with a 1.6L engine? If this is not correct, please let me know.

DTC P0240 is not a valid code for the vehicle listed above. Are you sure we are not talking about DTC P0420? If this is the case, then your catalytic converter is not working and most likely will need to be replaced. If you previously had fuel system problems, this is what most likely destroyed your catalytic converter - especially if the vehicle was driven fo some time with the fuel system problem. It is VERY common for this code to come up after other engine performance problems have been repaired. The reason for this is because the computer will not run the catalyst monitor if there are other problems in the ignition or fuel systems. So as long as these other problems exist, the computer has no idea what the condition of the catalyst is. Once the other problems are fixed, then the catalyst moitor will run. If the computer finds that the catalyst has been damaged and is not performing as designed, it will set DTC P0420.

Error Code P0240 on 2001 Ford Windstar


The catilytic convertor is at fault and needs replacing.
Have it checked first for a 02 sensor can throw this code as well. If the convertor is turning red on the outside it is junk status. Also the engine will sound like its starving for fuel
