During an open loop condition, the red inspectionlamp stays off.
Mode II (Mixture ratio feedback control monitor B): during a closedloop condition, the red inspection lamp turns on and off simultaneouslywith the green inspection lamp when mixture ratio is controlled withina predetermined value.During anopen loop condition, the green inspection lamp stays off. Mode I (Mixture ratio feedback control monitor A): during a closedloop condition, the green inspection lamp turns on when lean conditionis present and goes off when a rich condition is present.For description of modes, proceed as follows:.On all models, when ignition is turned Off during diagnosis, in eachmode, and then turned back On again after power to the ECU has dropped offcompletely, diagnosis will automatically return to Mode I.Note number of flashes, then immediately turn diagnostic mode selectorto Off position.Turn diagnostic mode selector on ECU to On position and wait untilinspection lamps flash.On Pathfinder, Pickup and Van models, proceed as follows: Note number of flashes, then immediately turn diagnostic mode selectorfully counterclockwise.Number of flashes displayed indicates correspondingmode. Turn diagnostic mode selector on ECU fully clockwise and wait untilinspection lamps flash.
On all models except Pathfinder, Pickup and Van, proceed as follows:.ATK Engines Remanufactured Crate Engine for 2012-2018 fits Nissan Altima & Rogoue with 2.5L L4 QR25DE $3,197.99 Ships directly from the manufacturer on 09/10/20. ? Be careful not to cause damage to circumference of oil seal.I've been needing to adjust my timing for a while now and just never got around to it. ? Using a drift of 56 mm (2.20 in) diameter, press oil seal in until it is flush with front end surface of front cover. ? To avoid skipped teeth, do not move crankshaft and camshaft until front cover is installed. ? After installing chain tensioner, remove stopper pin, and make sure the tensioner moves freely. ? Before and after installing chain tensioner, check again to make sure that mating marks have not slipped. NOTE: Before installing chain tensioner, it is possible to change the position of mating mark on timing chain for that of each sprocket for alignment.ĬAUTION:For the above reason, after the mating marks are aligned, keep them aligned by holding them with a hand.
? Install by lining up mating marks on each sprocket and timing chain as shown. ? After installation, make sure the mating marks have not slipped, then remove stopper pin and release tensioner.ĥ.Install timing chain and related parts. ? Be careful not to let mating marks of each sprocket and timing chain slip. If points change, temporarily fix the two mounting bolts on the chain guide and move the tensioner to match Therefore, bolt hole position of the three points could be changed during removal. NOTE: Chain guide and tensioner move freely with the caulking pin as the axle. ? Install it by lining up mating marks on each sprocket and timing chain.Ĥ.Install timing chain tensioner for balancer unit. ? Make sure that the crankshaft sprocket is positioned with mating marks on the block and sprocket meeting at the top. Do not make judgment by visual check alone.ģ.Install the crankshaft sprocket and timing chain for the balancer unit. ? Check tightening angle with an angle wrench or a protractor. Ī.Apply new engine oil to threads and seating surfaces of mounting bolts.ī.Tighten them to 45.2 - 51.0 N.m (4.6 - 5.2 kg-m, 34 - 37 ft-lb).Ĭ.Turn them another 90 - 95 degrees (Target: 90 degrees).ĭ.Fully loosen in the reverse order of tightening to 0 N.m (0 kg-m, 0 ft-lb).Į.Tighten them to 45.2 - 51.0 N.m (4.6 - 5.2 kg-m, 34 - 37 ft-lb).į.Turn them another 90 - 95 degrees (Target: 90 degrees). Refer to Balancer Unit Mounting Bolt Outer Diameter. ? When reusing a mounting bolt, check its outer diameter before installation. ? There are 26 links between the gold/yellow mating marks on the timing chain and 64 links between the camshaft sprocket gold/yellow link and the crankshaft sprocket orange/blue link, on the timing chain side without the tensioner.ġ.Make sure the crankshaft key points straight up.Ģ.Install the balancer unit and tighten the mounting bolts in the numerical order shown with the following procedure: ? There may be two color variations of the link marks (link colors) on the timing chain.
