Error 95 change oil warning lamp

Good afternoon,

This code is for the light as you indicated.

I attached a flow chart as well as a wiring diagram for you to view. It may be just the bulb that is bad creating an open circuit.

CIRCUIT DESCRIPTION
Ignition voltage is supplied directly to the change oil lamp on CKT 39. The Powertrain Control Module (PCM) controls the lamp by providing the ground path through CKT 1439.

When the PCM is commanding a component "ON, " the voltage of the control circuit should be "low" (near 0 volts). When the PCM is commanding the control circuit to a component "OFF, " the voltage potential of the circuit should be "high" (near battery voltage). The primary function of the driver is to supply the ground for the component being controlled.

Each driver has a fault line which is monitored by the PCM. The PCM will monitor the voltage at the driver.
If the fault detection circuit senses a voltage other than what is expected, the fault line status will change and the DTC will set.

The PCM monitors the distance the vehicle has traveled, Engine Coolant Temperature (ECT) and engine revolutions to determine when the next service interval is required. The PCM also estimates engine oil temperature based on various inputs. Once these calibrated values are attained, the PCM will ground CKT 1439 and the change oil lamp will illuminate.

The maximum mileage that can be accumulated before the PCM illuminates the change oil lamp is 7500 miles. However, the lamp may come "ON" sooner depending on engine load and temperature (trailer towing, high ambient temperatures, etc.).

DTC 95 WILL SET WHEN:
The PCM detects the wrong voltage potential for 26 seconds on CKT 1439.

ACTION TAKEN (PCM WILL DEFAULT TO)
DTC 95 will be stored in the PCM memory but will not turn "ON" the Malfunction Indicator Lamp (MIL).

DTC CHART TEST DESCRIPTION
Number(s) below refer to circled number(s) on the diagnostic chart.

1. Disconnecting the PCM connector will determine if CKT 1439 is shorted to ground or the PCM is at fault.

DIAGNOSTIC AIDS
Number(s) below refer to circled number(s) on the diagnostic chart. Inspect the harness and all related connectors including the PCM connections. These may cause an intermittent. Check for damaged or pushed out terminals. Refer to Instrument Panel.

Reset the change oil lamp by pressing reset button or by:
Ignition "ON, " engine "OFF."
Cycle accelerator pedal from closed throttle to Wide Open Throttle (WOT) 3 times within 5 seconds.

If lamp will not reset:
Monitor throttle angle using a Tech 1 (or equivalent) Scanner. Throttle angle must go from below 7.5 % to above 75 % for reset procedure to be recognized by the PCM.
If these values can not be attained, check accelerator cables for binding.
Check throttle shaft for binding or improper adjustment. Refer to Fuel Delivery and Air Induction.

Engine oil and filter should be changed when the change oil monitor is reset.
