AUTOMATIC FWD MODELS REMOVAL 1) Remove battery and battery tray. On 3000GT, remove undercover(s). On Eclipse turbo, drain and remove intercooler. On all models, remove air cleaner and case. Raise and support vehicle. Remove wheels. Disconnect control cables at transaxle. Drain transaxle fluid. 2) On Mirage 1.6L, disconnect tension rod. On all models, disconnect neutral safety switch connector, oil cooler hoses and electrical connectors from transaxle. Disconnect speedometer cable and throttle control cable (if equipped). Remove starter motor. 3) On Galant models with electronically controlled suspension, remove air compressor and bracket. Disconnect front height sensor rod at lower control arm. 4) On all models, remove upper transaxle-to-engine bolts. Remove engine undercover (if equipped). On all models, remove drive axle shafts. See FWD AXLE SHAFTS article in DRIVE AXLES. Separate lower control arms from struts for access to axle shafts (if necessary). 5) Remove front exhaust pipe (if necessary). On Eclipse 4WD, Galant 4WD and 3000GT, remove right member and gusset. On 4WD models, separate transfer assembly from transaxle. Reference mark transfer assembly-to-drive shaft and remove transfer assembly. 6) On all models, remove transmission inspection (dust) cover. Place index mark on torque converter and drive plate for reassembly reference. Remove torque converter-to-drive plate bolts. Push torque converter away from engine into transaxle. 7) Support transaxle with jack. Remove transaxle mounts bolts, mounting brackets and remaining transaxle-to-engine bolts. Slide transaxle assembly to right and lower to remove. CAUTION: Ensure torque converter is fully seated in transaxle before installation. Always install new snap rings on inner constant velocity joints. INSTALLATION 1) To install, reverse removal procedure. Tighten transaxle- to-engine bolts and torque converter-to-drive plate bolts to specification. See TORQUE SPECIFICATIONS table at end of article. 2) Ensure reference marks on torque converter-to-drive plate

Description NOTE: If DTC P0507 is displayed with other DTC, first perform the trouble diagnosis for the other DTC. The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects the actual engine speed and sends a signal to the ECM. The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily. The optimum value stored in the ECM is determined by taking into consideration various engine conditions, such as during warming up, deceleration, and engine load (air conditioner, power steering and cooling fan operation, etc.). On Board Diagnosis Logic DTC Confirmation Procedure NOTE: – If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test. – If the target idle speed is out of the specified value, perform EC-90, “Idle Air Volume Learning”, See: Programming and Relearning/Idle Air Volume Learning before conducting DTC Confirmation Procedure. For the target idle speed, refer to the “SERVICE DATA AND SPECIFICATIONS (SDS)”.

LUBRICATION SERVICE INTERVALS Transaxle/Transmission Check fluid level every 12 months or 15,000 miles. Change fluid and filter every 30,000 miles. If vehicle is operated under severe conditions, change fluid more often. If severe darkening of fluid and strong odor are noted, bands should also be adjusted. Transfer Case On 4WD and AWD models, change transfer case fluid every 30, 000 miles. CHECKING FLUID LEVEL RECOMMENDED FLUID Transaxle/Transmission Use Chrysler Plus/Mitsubishi Plus ATF, Dexron or Dexron-II ATF.

1. Turn the ignition OFF. 2. On the Accord, remove the screws securing the underdash fuse box to its mount.
Remove see mount 3. On Preludes, remove the dashboard under cover; remove the fuel cut?off relay from the fuse mount 4. Disconnect the fuel line at the fuel filter in the engine compartment. Connect a pressure gauge 5. Turn the ignition key ON until pressure on the gauge stabilizes, then turn the key OFF.
Carbureted GENERAL INFORMATION On these vehicles, the engine management system is considered part of the emission control
system. The major components include the carburetor(s), feedback control system, the air injection system, a throttle control system and the EGR system. The system consists of sensors and switches that feed information to the Electronic Control Unit (ECU), which will then operate several solenoid valves to maintain the ideal air/fuel ratio under all conditions.
