Honda Civic/Acura Integra

since 1994 of release

Repair and car operation

Check and adjustment of turns of idling (each 48 000 km of run or time in 24 months)

PERFORMANCE ORDER

1. Frequency of rotation of the engine is called as turns of idling at the released pedal of an accelerator. This parameter is among critical, defining both operation of the engine generally, and serviceability of functioning of its various subsystems. Before starting check or adjustment of turns of idling make sure that a control lamp “Check the engine” it is not included. The air purifier and spark plugs should be in a good condition, the PCV system to function regularly. Make sure of correctness of installation of a corner of an advancing of ignition.
2. According to instructions of manufacturers connect a manual tachometer.
3. Cock the parking brake and block wheels. Make sure that transmission is transferred to neutral transfer (RKPP) or established in the situation "R" (AT).
4. Start the engine and at frequency of rotation of 3000 rpm warm up it to normal working temperature. As soon as the fan of system of cooling will turn on, dump engine turns to the single.
5. On all Integra models and all Civic models, except D16Y5 of release 1996 and 1997 with CVT, release D16Y8 from 1996 to 1998 from AT, all D16Y7 and D16Y5 1998 g вып. with CVT execute the following procedures:
   a) Muffle the engine and disconnect electroconducting from the valve of stabilization of turns of idling (IAC) (see. Head of the Power supply system and release). On all Integra models of 1998 вып., and also the Civic D16Y8 models with RKPP and D16Y5 with CVT of 1998 вып. disconnect the electromagnetic valve of a purge of a coal adsorber;
   b) Start the engine and, having slightly squeezed out an accelerator pedal, fix its turns on value 1000 in a minute. Slowly release a pedal, having dumped turns to the single. Make sure that all consumers of the electric power are disconnected, and the fan of a radiator and the conditioner of air do not function;
   c) For the Civic models turns of idling should lie in a range 450 ± 50 in a minute, for all Integra models, except В18С5 1998 g вып. – 480 ± 50 in a minute, for Integra of В18С5 1998 g вып. – 550 ± 50 in a minute;

d) If turns of idling need adjustment, uncover and rotation of the adjusting screw bring them into norm (see an accompanying illustration). Adjustment make step by step with a step in 1/4 turns of the screw;
And — the Adjusting screw
In — the IAC valve Socket (on the majority of models it should be disconnected)

   e) Muffle the engine and connect electroconducting to IAC valves and purges of a coal adsorber;
   f) For ten seconds take from the assembly block in an impellent compartment a safety lock of fires of a backing on 7.5 And is will lead to cleaning of memory of codes of malfunctions of ESM;
   g) Start the engine and wait about a minute, let's be stabilized by idling turns. Consider indications of a tachometer and compare them to requirements of Specifications or the values given on a label of VECI (in case of different interpretations it is necessary to give preference to the last).
6. On stipulated in the paragraph 5 the Civic models, without disconnecting the IAC valve, execute the following procedures:
   a) Start the engine and wait about a minute, let's be stabilized by idling turns. Consider indications of a tachometer and compare them to requirements of Specifications or the values given on a label of VECI (in case of different interpretations it is necessary to give preference to the last).
   b) If turns of idling need adjustment, remove a cap and rotation of the adjusting screw bring them into norm. Adjustment make step by step with a step in 1/4 turns of the screw;
7. On all models include To/in and choose the maximum high-speed mode of functioning of the fan of a heater. Frequency of rotation of the engine should raise on 50÷100 in a minute, violation of serviceability of functioning of the IAC valve or a control system (otherwise takes place see. Head of the Control system of the engine).
