Possible Cause
 Low coolant, high
ambient, plugged
radiator, bad CT
sensor.
 Problem with the
throttle body or
leads.
 Problem with the TP
sensor in the throttle
body or the leads.
 Problem with the TP
sensor in the throttle
body or the leads.
 Problem with the TP
sensor in the throttle
body or the leads.
 Problem with the TP
sensor in the throttle
body or the leads.
 KG2204T engine
with turbocharger
only.
 Problem in the
turbocharger
wastegate control
circuit.
 KG2204T engine
with turbocharger
only.
 KG2204T engine
with turbocharger
only.
 Problem in the boost
pressure sensor
signal circuit.
 KG2204T engine
with turbocharger
only.

Corrective Action
 Check coolant level, clean the
radiator from debris.
 Check Coolant outlet temp with IR
Gun.
 Troubleshoot the CT sensor.
Refer to Section 4.3.
 Replace CT sensor. Refer to
Section 5.2.
 Troubleshoot the TP sensor
leads. Refer to Section 4.11.
 Replace the throttle body. Refer
to Section 5.1.
 Troubleshoot the TP sensor
leads. Refer to Section 4.11.
 Replace the throttle body. Refer
to Section 5.1.
 Troubleshoot the TP sensor
leads. Refer to Section 4.11.
 Replace the throttle body. Refer
to Section 5.1.
 Troubleshoot the TP sensor
leads. Refer to Section 4.11.
 Replace the throttle body. Refer
to Section 5.1.
 Troubleshoot the TP sensor
leads. Refer to Section 4.11.
 Replace the throttle body. Refer
to Section 5.1.
 Check wastegate and solenoid
plumbing.
 Check wastegate solenoid
operation.
 Check for proper preload and
opening pressure on the
wastegate.
 Compare manifold pressure and
boost pressure sensor values with
engine stopped. If values do not
match, one of the sensors is
incorrect for the application or is
out of calibration. Replace the
sensor that is reading incorrectly.
 Check the electrical connection to
the boost pressure sensor.
 Check the sensor signal circuit for
a short to ground.
 Replace the boost pressure
sensor.
 Check the sensor signal for a
short to power.
 Check the sensor ground signal
to ensure it is not disconnected.
 Replace the boost pressure
sensor.
 Not applicable
 Not applicable
