OUTLINE
OUTLINE

from the current 626 (GF, GW) RF Turbo engine models, except for the following features: (See 626, 626
Station Wagon Workshop Manual Supplement 1614-10-98D)
FEATURES
Improved serviceability
• By adding the PIDs “RPM DES” (target engine speed) and ‘TP2 V” (accelerator position signal voltage for
monitoring) to the PID/DATA MONITOR items, serviceability has been improved.
Improved Reliability
• A potentiometer-type (two-accelerator position signals circuit) accelerator position sensor has been adopted tol
improve the reliability of the accelerator position sensor. Due to the change of the accelerator position sensor
type, a detection condition item has been added to DTC P0120 for accelerator position sensor signal circuit.
