System Diagnosis: Notes

1994 Plymouth Sundance Base, 2D Hatchback, 2.2 D, AutomaticSECTION Notes
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

The self-diagnostic capabilities of this system, if properly used, can simplify testing. Powertrain Control Module (PCM) monitors several different engine control system circuits.

If a problem is sensed with a monitored circuit, Malfunction Indicator Light (MIL) will illuminate and PCM will enter limp-in mode. In limp-in mode, PCM attempts to compensate for particular component failure by substituting information from other sources. This allows vehicle operation until proper repairs are made.

Once trouble codes are known, to determine the questionable circuit, refer to CHARGING SYSTEM TROUBLE CODES  table under ENTERING ON-BOARD DIAGNOSTICS.

Perform circuit tests to repair or replace components as required. If problem is repaired or ceases to exist, the PCM will cancel that trouble code after 50 ignition on/off cycles. To clear codes, refer to appropriate ERASING TROUBLE CODES procedure under ENTERING ON-BOARD DIAGNOSTICS .

A specific trouble code results from a particular system failure. Components in that system are not necessarily the reason for that failure. The trouble code does not condemn a specific component, it indicates a circuit malfunction.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
