CODE MEANINGS

Code Definitions for FORD Engines with MCU Computer System

(Microprocessor Control Unit)

Code definitions are

listed in this section

• Many of the codes

listed may not apply to
your vehicle.

• Use the definition that

applies to your engine
type: In-Line 4 or 6
cylinder (I-4, I-6) or V-6
or V-8.

• Follow vehicle service

manual procedures to
find the cause of the
code.

Remember:

1) Visual inspections are

important!

2) Problems with wiring

and connectors are
common, especially for
intermittent faults.

3) Mechanical problems

(vacuum leaks, binding
or sticking linkages,
etc.) can make a good
sensor look bad to the
computer.

11

“High Altitude” computer
adjusted for operation at
high elevations such as in
Denver, Colorado.

I-4

(All except High

Altitude): System pass.

I-4

(High Altitude only):

Altitude (ALT) circuit is
open.

I-6:

System pass.

V-6

(All except High Altitude):

System pass.

V-6

(High Altitude only):

Altitude (ALT) circuit is
open.

V-8

(All except High Altitude):

System pass.

V-8

(High Altitude only):

Altitude (ALT) circuit is
open.

12

V-8:

RPM out of

specification – Throttle
Kicker (TK) system.

25

V-8:

Knock Sensor (KS)

signal not detected during
Key On Engine Run
(KOER) Self-Test.

33

All Engines:

Key On

Engine Run (KOER) Self-
Test not initiated.

41

All Engines:

Exhaust

Gas Oxygen (EGO)
sensor: voltage signal
always “lean” (low value) –
does not switch.

42

All Engines:

Exhaust

Gas Oxygen (EGO)
sensor: voltage signal
always “rich” (high value) –
does not switch.

44

All Engines:

Exhaust

Gas Oxygen (EGO)
sensor: signal voltage
indicates “rich” (high value)
with Thermactor air
switched upstream to the
exhaust manifold (a “lean”
air/fuel condition).

45

All Engines:

Thermactor

air flow is always upstream
(going to exhaust

manifold).

46

All Engines:

Thermactor

Air System unable to
bypass air (vent to
atmosphere).

51

I-4:

Low or Mid

Temperature Switch circuit
is open when engine is hot.

I-6:

Low Temperature

Vacuum Switch circuit is
open when engine is hot.

V-6:

Hi or Hi/Low Vacuum

Switch circuit is always
open.

V-8:

Hi or Hi/Low Vacuum

Switch circuit is always
open.

52

I-4

(car): Idle Tracking

Switch (ITS) – voltage does
not change from closed to
open throttle. (Closed
throttle checked during Key
On Engine Off condition.
Open throttle checked
during Engine Running
conditions.)
I-4 (truck): Idle/Decel
Vacuum Switch circuit
always open.

I-6:

Wide Open Throttle

(WOT) Vacuum Switch
circuit is always open.

53

I-4:

Wide Open Throttle

(WOT) Vacuum Switch
circuit is always open.

I-6:

CROWD Vacuum

Switch circuit is always
open.

V-6:

Dual Temperature

Switch circuit is always
open.

V-8:

Dual Temperature

Switch circuit is always
open.

54

V-6:

Mid Temperature

Switch circuit is always
open.

V-8:

Mid Temperature

Switch circuit is always
open.

55

I-4:

Road Load Vacuum

Switch circuit is always
open.
