Code 11 Test (Part 2 of 2)
Connect Breakout Box if not already connected.
Turn ignition switch OFF. Disconnect ECM con-
nector [11]. Check for continuity between connec-
tor [88] Terminal A (R/W wire) and Pin 1 of
connector [11]. Continuity present?
NO
Continued from Code 11 Test (Part 1 of 2).
Unplug TP sensor connector [88]. Measure voltage between
Terminal A (R/W wire) (+) and C (BK/W wire) (-) with ignition ON.
Is voltage 5.0 +/- 0.25?
YES
Connect Breakout Box if not
already connected. Check
resistance between ECM Pin
2 on connector [11] to chassis
ground. Is resistance greater
than 1 megaohm?
Find short to ground
on V/Y wire.
NO
Check continuity from
Pin 2 of connector [11]
to Terminal B on
connector [88].
Continuity present?
YES
Locate and repair
open in V/Y wire.
NO
Replace TP sensor.
See 4.37 THROTTLE
POSITION SENSOR.
YES
Locate and repair open
in R/W wire.
NO
Check continuity
between connector [88]
Terminal B (V/Y wire)
and Pin 2 of connector
[11]. Continuity present?
YES
Locate and repair open
in V/Y wire.
NO
Check continuity between con-
nector [88] Terminal C (BK/W)
and Pin 7 of connector [11].
Continuity present?
YES
Locate and repair open
in BK/W wire.
NO
YES
Locate and repair short
between R/W and BK/W
wires. Reconnect [14].

Clear codes and confirm proper operation with no
check engine lamp. Codes can be cleared using
DIGITAL TECHNICIAN (Part No. HD-44750).
Disconnect bank angle sensor
connector [134]. Measure resistance
between connector [88] Terminal A
and Terminal C. Is resistance greater
than 1 megaohm?
Measure resistance between connec-
tor [88] Terminal A and Terminal C. Is
resistance greater than 1 megohm?
NO
Replace BAS.
NO
Disconnect cam position sensor
connector [14]. Measure resistance
between connector [88] Terminal A
and Terminal C. Is resistance greater
than 1 megaohm?
YES
Replace cam position
sensor.
YES
