NO.27 CONSTANT VOLTAGE
A6E398018881W29
Diagnostic procedure
27
CONSTANT VOLTAGE
DESCRIPTION
Incorrect constant voltage
POSSIBLE CAUSE
•
Constant voltage circuit malfunction
Note
•
TP sensor uses constant voltage.
STEP
INSPECTION
RESULTS
ACTION
1
Disconnect TP sensor connector where constant
voltage circuit inspection failed.
Turn ignition switch to ON position.
Measure voltage between following TP sensor
connector terminals:
•
Constant voltage terminal - GND terminal
Is constant voltage
greater than 6.0 V
?
Yes
Go to Step 13.
No
Go to next step.
2
Is voltage across battery terminals
greater than
10.5 V
?
Yes
Go to next step.
No
Inspect charging system.
3
Turn ignition switch off.
Leave TP sensor connector disconnected.
Measure voltage between battery positive
terminal and GND (between PCM and TP
sensor) circuit at appropriate sensor connector.
Is voltage
greater than 10.5 V
and
within 1.0 V
of battery voltage?
Yes
Go to next step.
No
Go to Step 8.
4
Note
•
Purpose of this step is to determine if
WDS or equivalent is communicating with
PCM.
Turn ignition switch to ON position.
Attempt to access ECT PID.
Can ECT PID be accessed?
Yes
Go to Step 7.
No
Go to next step.
5
Turn ignition switch off.
Disconnect TP sensor and PCM connectors.
Turn ignition switch to ON position.
Measure voltage between PCM connector
terminals 2Y and 2AB.
Is voltage
greater than 10.5 V
?
Yes
Go to next step.
No
Repair open circuit between PCM terminal 2Y and
main relay.
6
Leave TP sensor and PCM connectors
disconnected.
Measure resistance between PCM connector
terminals 2Y and 2AB.
Is resistance
greater than 10,000 ohms
?
Yes
Inspect for constant voltage at suspect sensor
connector again.
No
Repair constant voltage circuit short to GND.
7
Turn ignition switch off.
Leave TP sensor disconnected.
Disconnect PCM connector.
Measure resistance between PCM connector
terminal 2K and constant voltage circuit at
appropriate sensor connector.
Is resistance
less than 5.0 ohms
?
Yes
Inspect for constant voltage at suspect sensor
connector again.
No
Repair open constant voltage circuit.
8
Note
•
Purpose of this step is to determine if
WDS or equivalent is communicating with
PCM.
Reconnect TP sensor connector.
Turn ignition switch to ON position.
Attempt to access ECT PID.
Can ECT PID be accessed?
Yes
Go to next step.
No
Go to Step 11.
