Where is the location of the ECM on a 1998 ford explorer?


ECM (Engine Control Module) is the old name to the new PCM
(Powertrain Control Module) denomination; this unit performs many functions on your car. The module accepts information from various engine sensors and computes the required fuel flow rate necessary to maintain the correct amount of air/fuel ratio throughout the entire engine operational range.

Based on the information that is received and programmed into the PCM's memory, the PCM generates output signals to control relays, actuators and solenoids.

The module is mounted under the hood on the firewall. On 493-94 models, it is mounted low on the firewall, near the left-hand fender (drivers side). On 495-99 models, it is mounted high on the firewall offset to the right-hand side of center.

  1. Disconnect the negative battery cable.
  2. Disengage the wiring harness connector from the PCM by loosening the connector retaining bolt, then pulling the connector from the module.
  3. Remove the two nuts and the PCM cover.
  4. Remove the PCM from the bracket by pulling the unit outward.
To install:
  1. Install the PCM in the mounting bracket.
  2. Install the PCM cover and tighten the two nuts.
  3. Attach the wiring harness connector to the module, then tighten the connector retaining bolt.
  4. Connect the negative battery cable.

Hope helps (remember comment and rated this).

Engine light is on


There is a Technical Service Bulletin (NTB04-037a) for this code to check the Engine Control Module (ECM) part number and if the ECM part number is listed in the TSB, it requres the dealer to reprogram the ECM. If the ECM part # is not listed, the TSB does not apply and then the problem is likely a defective Air/Fuel (A/F) Sensor.
