Table a. MI-04 Diagnostic Fault Codes (Flash Codes)
DFC Probable Fault
26 ETCSticking
Throttle plate sticking inside the
throttle body or the ETC driver signal
is open
27 PredictedTPSDifference
Measured TPS1 is different than
SECM Calculated throttle position
28 ETCSpringTestFailed
Upon initial
throttle return spring has become
weak
29 ETCDriverFault
Throttle driver over-current or driver
signals shorted
33 MapSensorInputLow
MAP signal disconnected, open
circuit or sensor malfunction
(Expected
connector is unplugged
CODES: 33 & 38)
34 MapSensorInputHigh
TMAP sensor failure or shorted
circuit
37 IATSensorInputLow

Operation Section
Corrective Action, First Check
Check for debris or obstructions
inside the throttle body
Check throttle-plate shaft for
bearing wear
Check the ETC driver wiring for an
open circuit
Check for manifold leaks between
the throttle and the engine
Note: Fault Code 27 is predicted
TPS. This fault means that the
throttle and our calculated prediction
for throttle do not agree. This code
often comes up as suspected during
transient manuevers. It is not system
trouble. If the fault really sets, then
the engine will shut down.
Perform throttle spring test by cycling
the ignition key and re-check for fault
Check ETC driver wiring for a
shorted circuit
Check TMAP connector and MAP
signal wiring for an open circuit
Check TMAP connector and MAP
signal wiring for a shorted circuit
Check TMAP connector and IAT
signal wiring for a shorted circuit
Check TMAP connector and IAT
signal wiring for an open circuit
