1994 Nissan Maxima J30 Service Manual (200 P.)

Detailed undefined Calibration Manual: Car 1994 Nissan Maxima J30 Series Service Manual (200 P.) Assembly-Guide

Model-Designation: Nissan Maxima J30 Series — 1994 // Documentation-Type: Comprehensive technical resource for factory-authorized service procedures // Model-Designation: Detailed technical specifications and maintenance protocols.

Major sections address the following systems: The manual presents information on engine mechanical assembly covering compression testing and cylinder head procedures, then transitions to fuel and emission control mechanisms including multiport fuel injection system parameters, and proceeds through cooling system maintenance specifications, followed by brake system inspection data, and concludes with electrical and body component documentation.

Engine Systems & Specifications: Special procedures are addressed for engine lubrication circuit maintenance, with oil pressure check points documented at idle speed (59 kPa minimum) and 3,200 rpm (363–451 kPa range). Proper configuration of timing belt installation requires alignment of punchmarks on camshaft and crankshaft sprockets to TDC position. Valve clearance reference data is included for both intake and exhaust valve components, with specific mentions of valve spring pressure standards and rocker shaft clearance limits.

Transmission & Drivetrain: Verification procedures are included for manual transaxle oil level checking and automatic transmission fluid condition assessment using dipstick readings at operating temperatures. The document includes detailed procedures for both M/T and A/T models, with fluid capacity ranges and recommended refill specifications clearly marked. Wheel balancing data is documented, specifying maximum allowable dynamic unbalance of 2 oz at rim flange and static unbalance of 20 oz.

Cooling & Lubrication Systems: Repair information is provided for water pump inspection procedures, thermostat valve opening temperature thresholds (82°C standard), and radiator cap relief pressure specifications (78–98 kPa range). The manual documents torque specifications for engine drain plugs (34–44 N-m range) to ensure proper seal integrity. Oil filter specifications and engine oil capacity ranges are clearly delineated for both engine models, with viscosity grade recommendations tied to ambient temperature ranges.

Braking & Safety Systems: The document includes coverage of disc brake rotor repair limits (20.0 mm standard thickness for VG30E), pad wear limit specifications, and drum brake lining thickness reference data (4.5 mm standard, 1.5 mm minimum). Parking brake adjustment procedures are documented, referencing number of notches (8–10 range) for proper engagement. Seat belt assembly inspection points and anchor bolt torque values are specified.

Electrical & Control Components: The manual provides comprehensive documentation of ECCS (Engine Control Module) system architecture, fuel injection timing control logic, and ignition system operation. Sensor specifications including camshaft position sensor signal generation (360 one-degree slits, 6 one-hundred-twenty-degree slits) and mass air flow sensor measurement principles are described. Power transistor amplification function and idle air control valve step motor operation are documented, with target idle speed values referenced (750 rpm VG30E standard, 760 rpm VE30DE standard).

The service manual documents torque specifications for cylinder head bolts (29–64 N-m in two-step angular tightening procedure) to ensure proper joint separation prevention and gasket seal integrity. Connecting rod bearing cap nuts and main bearing fasteners are similarly specified for both standard and angular tightening protocols, with clearance inspection procedures provided using plastigage measurement technique.
