My 2008 aveo ls will not start. the serpentine belt broke and we replaced that as well as the battery. then we checked spark plugs and fuses added gas and tried spraying starter fluid into throttle bo

  • Well, if the belt broke, it may have torn some wires loose in the front of the engine. The most likely one that may have been torn loose would be the crankshaft position sensor, which is located near the bottom of the crankshaft pulley. Check wiring and the crankshaft position sensor for quality condition.

I just replaced my accessory belts on my 98 subaru legacy outback the car drove fine no other problems at time of replacement that i could tell...about a week and a half later started car it sounded funny...

Sounds like changing the belt had nothing to do with the problem unless something was disconnected or damaged. Maybe you already know all the problem codes, but if not here is a list of them. Also, when you make a reapair on one of the codes you have to reset the codes. They stay in memory until you rested them. So if you reset the 336 and 341 codes my disappear. Reseting the codes doesn't have anything to do with not starting. Make sure nothing was accidentaly disconnected or damaged. The throttle sensor is on the throttle which is in the housing that the air cleaner connectes with. I'm unsure where the Knock sensor is located. The catalyst sensor is probably one of the oxygen sensors in the exhaust pipes, the farthest away from the engine. Your discription of how the care died sounds to me like the throttle sensor.
The problem you have withour having someone check all these item with a system scanner, is you don't know which is defective or if they all are. When you purchase any of these sensors, they are expensive and they are not returnable once you open the packaging. If it not a connection or broken item that is ovbious, I recommend you have a quilified shop check the problem. Guessing can cost a lot for no reason.

P0122 Throttle/Pedal Position Sensor/Switch "A" Circuit Low Input
P0325 Knock Sensor #1 - Circuit Malfunction (Bank #1 or Single Sensor)
P0336 Crankshaft Position Sensor "A" Circuit Range/Performance
P0341 Camshaft Position Sensor Circuit Range/Performance
P0420 Catalyst System Efficiency Below Threshold (Bank #1)

Good luck

Thanks for using FixYa.

Check engine light came on trouble shooting code is P 0122

Code P0122 is a TPS (Throttle Position Sensor) sensor out of range.

The operating range of the TPS is about .5 to 4.8 volts. .5 at idle 2.5 at half throttle and 4.8 at full throttle.

This can be checked easily with a scanner. But can be checked with a multi-meter.

You can try replacing it for a start and see what happens

  • Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  • 4. Locate the throttle position sensor.

  • Throttle position sensor

  • 5. Disconnect the electrical connector from the throttle position sensor.

  • Electrical connector removed
6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.

1994 chevy lumina van. It will start and idle but stalls when gas

Try replacing the throttle position sensor. I had the same problem in my truck. It would start and run for a bit but as soon as you let off of the pedal, it would die. Try it and see if it works.
