PINPOINT TEST D : Incorrect Temperature Gauge Indication

D2 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO SELF-TEST

Are any DTCs recorded?

Yes	REFER to ENGINE CONTROLS - SYMPTOM CHARTS (EXCEPT DIESEL & HYBRID) .
No	GO to D3.

D3 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST

Are any DTCs recorded?

Yes	For DTC U0100:00, GO to Pinpoint Test AR . For all other DTCs, REFER to DTC Chart: IPC .
No	GO to D4.

D4 CARRY OUT THE TEMPERATURE GAUGE ACTIVE COMMAND USING THE SCAN TOOL

Command the temperature gauge according to the tables:

Base IPC

Scan Tool Command	Gauge Position
0% [-60 ° C (-76 ° F)-38 ° C (100 ° F)]	Beginning of cold (C) (fill color blue)
15% [59 ° C (138 ° F)]	End of cold (C) (fill color blue)
35% [79 ° C (174 ° F)]	Just below the center of the gauge (mid-range, fill color gray)
65% [120 ° C (248 ° F)]	Just below the beginning of hot (H) (fill color gray)
80% [121 ° C (250 ° F)]	Just above hot (H) (fill color red)

Optional IPC

Scan Tool Command	Gauge Position
0% [24 ° C (76 ° F)-38 ° C (100 ° F)]	Full cold (C)
15% [59 ° C (138 ° F)]	Beginning of the normal range
45% [83 ° C (181 ° F)-109 ° C (228 ° F)]	Center of the gauge
85% [120 ° C (248 ° F)]	End of the normal range
95% [122 ° C (252 ° F)]	Hot (H) (red line)

Does the temperature gauge operate according to the above specifications?

Yes	GO to D5.
No	Refer to IPC Hardware Testing .

D5 CHECK THE PCM TEMPERATURE PID

Select the PCM temperature PID (Cylinder Head Temperature (CHT)). With the engine running, monitor the PCM temperature PID.

Does the PCM PID agree with the position of the temperature gauge indication?

Yes	The temperature gauge is operating correctly at this time.
No	Refer to IPC Hardware Testing .

Yes	GO to D2.
No	REFER to Engine Cooling .
