SOURCE: 1999 Dodge Caravan with a code 23. What does that

OBD-II Trouble Code Technical Description
A P0020-023 code refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020-023 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn't contain cylinder #1.

Causes
A code P0020-023 may mean that one or more of the following has happened:

  • Faulty oil control valve (OCV)
  • Open or short in the VVT/VCT circuit
  • Open or short in the OCV / solenoid valve
  • Damaged computer (PCM)
Possible Solutions
Some recommended troubleshooting and repair steps are:
  • Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required
  • With a warm engine, test the operation of the OCV, replace/repair as needed

SOURCE: Check Engine Light

It is for the radiator fan relay control circuit.It means there is a problem in the cooling fan relay circuit.Could be the relay,wiring,or the fans.Check the fuses and relay over if it looks good then you have to take it in to get it diagnosed.You need a scan tool and you also need to know how to use a multimeter.Hope this helps.Good luck.

SOURCE: code reads P0340 Camshaft position Sensor circuit

That makes the computor think the timing is off. Replace the sensor and see if that does it. You will then have to have the code cleared (erased) or the light will come back on/stay on.

Someone will have to figure out if you are dealing with a no spark or no fuel problem when it won't start.
Could be a long list of causes depending on which issue.

When it won't start someone will need to find out if you are dealing with a no-spark or no-fuel problem to proceed.
If the check engine light is on you should get the computer scanned for trouble codes.

Car want start


If it cranks but won't start, you'll have to figure out if it is fuel or ignition related to proceed.
Could be a long list of components including relays, fuses, sensors, coil and fuel pump.
Check for fuel pressure and spark at the plugs.
Also check the computer for trouble codes.

My '97 ford taurus isnt kicking over while tryn to start it up


Anything done to car, or happened recently that might affect this?
If starter fluid doesn't work, and starter is cranking normally (too fast may point to a timing belt broke, too slow may mean battery run down and not producing sufficient spark), there's still a problem in your ignition. Pull a sparkplug or two. After cranking a little they should be wet with gas. Check for compression while a plug is out: hold your finger over plug hole when cranking. You should feel pressure buildup and release over and over as long as cranking.
A properly timed engine needs spark, fuel, and compression to start. Keep reviewing your procedure. Something is not right.
You may want to have the computer scanned for possible trouble codes. Check plug wires for proper routing. Were plugs gapped right?
