P0218-HIGH TEMPERATURE OPERATION ACTIVATED
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The DTC is intended as an informational DTC to aid the technician in determining the root cause of a customer
dirveability issue. The DTC is also intended to alert the technician to determine if a cooling system malfunction has
occurred or if an additional transmission air to oil cooler is needed to support the customers driving behavior.
When Monitored:
Whenever the engine is running.
Set Condition:
Immediately after a Overheat shift schedule is activated when the Transmission temperature exceeds 127° C
or 260° F.
Possible Causes
H I G H T E M P E R AT U R E O P E R AT I O N A C T I VAT E D
TORQUE CONVERTER CLUTCH SLIPPING / NOT ACTIVATING
EXCESSIVE TIME IDLING IN GEAR
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Diagnostic Test
1.HIGH TEMPERATURE OPERATION
This DTC is an informational DTC designed to aid the Technician in diagnosing shift quality complaints.
This DTC indicates that the transmission has been operating in the
Overheatshift schedule which may generate
a customer complaint.
The customer driving patterns may indicate the need for an additional transmission oil cooler.
Verify proper Engine cooling system operation which would affect proper transmission operation.
Verify proper torque converter clutch operation.
With the scan tool, check the DTC EVENT DATA to help identify the conditionsin which the DTC was set.
If there are no possible causes remaining, view repair.
Repair
Repair the cause of transmission overheating. Refer to the Service Information for the proper repair
procedure. Make sure to check for any Service Bulletins pertaining to thisproblem.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)

When Monitored:
With the engine running and the PCM has closed the Transmission Control Relay.
Set Condition:
If the battery voltage of the Transmission Output circuit(s) to the PCM is less than 10.0 volts for the period of
15 seconds. Note: P0562 generally indicates a gradually falling battery voltage or a resistive connection(s) to
the PCM. The DTC will also set if the battery voltage sensed at the PCM is lessthan 6.5-volts for 200ms or
where the Transmission Output circuits are less than 7.2-volts for 200ms.
Possible Causes
RELATED CHARGING SYSTEM DTC’S

Theory of Operation
Friction element distress could result from an insufficient supply voltage to properly control the solenoids. To prevent
this possibility, the battery voltage is monitored and the system is placed in logical limp-in if the battery voltage
drops below the limit.

When Monitored:
Continuously with the ignition on.
Set Condition:
The DTC will set if the controller detects an invalid PRNDL code which lastsfor more than 0.042 seconds.
Possible Causes
SHIFTER OUT OF ADJUSTMENT
TRS SENSE CIRCUIT OPEN
TRS SENSE CIRCUIT SHORT TO GROUND
TRS SENSE CIRCUIT SHORT TO VOLTAGE

POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The T1, T2, T3, T41, or T42 (C1 - C5) Sense circuits communicate the shift lever position to the Transmission
Control System. Each circuit is terminated at the transmission by a switch(TRS). Each switch can be either open
or closed, depending on the shift lever position. The PCM can decode this information and determine the shift lever
position.
Each shift lever position has it own unique combination of closed and open switches. This is called a PRNDL code.
There are 5 switches, therefore: there are many possible combinations of open and closed switches (codes). There
are 12 valid codes: two for neutral, one for each other gear position (5), and five temporary (transition zone) codes.
The remainder of the codes should never occur, these are called invalid codes.
Diagnostic Test

Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
The transmission system uses two speed sensors, one to measure input RPM and one to measure output RPM.
These inputs are essential for proper transmission operation. Therefore, the integrity of this data is verified through
the following checks:
1) When in gear, if the gear ratio does not compare to a known gear ratio, the corresponding in-gear trouble code
is set (DTCs P0731–36).
2) An excessive change in input or output speeds indicating signal intermittent which may result in the DTCs P0715
and/or P0720 to set.
3) If the common speed sensor ground circuit is lost, both sensor inputs will read the signal from the input speed
sensor at idle in neutral. Since the input speed sensor reads 60 teeth from the input clutch hub and the output
speed sensor reads 30 teeth from the park gear, the result is an apparent speed ratio of 1:2 and may cause the
DTC P1794 to set when at a stop.
Diagnostic Test
