SOURCE: What is the diagnostic codes P 0700 P1684 p0442

P0700: EATX Controller DTC present
P1684: Battery was desconnected
P0442: EVAP leak monitor medium (.040). Leak detected.
P0455:
EVAP leak monitor large. Leak detected.
P0456: EVAP leak monitor small (.020). Leak detected.

I suggest check the lines and flow it down to the ldp (leak detection pump) that is just behind the steering gear under the van It has a wire connector and 2 large EVAP hoses. look for any split or crack then follow the lines back to the tank. Even a small crack is a leak.

Hope helped with this. Remember rated this help. Good luck.

SOURCE: I have fault codes P1684 & P0340 on my 2002

P1684 The battery has been disconnected within the last 50 starts.

P0340


This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
Symptoms Symptoms can include:

  • Hard starting or no start
  • Rough running / misfiring
  • Loss of engine power
Causes A code P0340 could mean one or more of the following has happened:
  • a wire or connector in the circuit could be grounded/shorted/broken
  • the camshaft position sensor may have failed
  • the PCM may have failed
  • there exists an open circuit
  • the crankshaft position sensor may have failed
Possible Solutions With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
  • Visually inspect all the wiring and connectors in the circuit
  • Check for continuity in the circuit wiring
  • Check the operation (voltage) of the camshaft position sensor
  • Replace the camshaft position sensor as required
  • Check the crankshaft position circuit as well
  • Replace circuit wiring and/or connectors as required
  • Diagnose/replace the PCM as required

Camshaft Position Sensor


P0340 Camshaft Position Sensor "A" Circuit Bank 1 or Single Sensor

P0700 Transmission Control System (MIL Request)

The code P1684 is real easy. The computer is stating that the battery has been disconnected within the last 50 starts.

Hi, a P1684 is "Battery Disconnected Within Last 50 Starts". I wouldn't worry about that too much.

The P0340 is "Camshaft Position Sensor Circuit Malfunction". I'd definitely look into that code. I found a great article specific to the p0340 code - http://www.obd-codes.com/p0340 - it should give you an idea on what to look for, test, replace, etc. Good luck!
