1983-1986

I don't have much researched out on this era

Engine is a 2.0L 2S-E

There was an option for a 1.9L Diesel 1CLC and in 86 a 2.0L turbo diesel 2C-T

1987-1991

Body style - 1987-1991

Updated engine 2.0L 3S-FE

Mostly unchanged for this year range.

1992-1993

First year Camry received the 2.2L 5S-FE engine

Body style - 1992-1996

1994-1995

California emissions got a new crank sensor pattern (24 point instead of 4 point) and also 4 injector channels instead of 2

Federal emissions mostly the same as 92-93

1996

Updated crank sensor design, on crank 36-2 pattern

1997-1999

Body style - 1997-2001

Ignition system rework, dropped the distributor for two smart coils in waste spark configuration

TPS updated design and connector, removal of the idle signal wire.

Engine Immobilizer became an option in 1998.

Fuel pressure and fuel system design reworked, pressure increased to 50psi and fuel pressure regulator moved from injector rail to fuel tank sending unit

2000 Fed Emissions

Same as 1997-1999 except computer connectors physically changed.

2000 California Emissions

Updated IAC design, instead of an open/close signal, it uses PWM to control how much to open it.

2001

Same as 2000 California Emissions

2002

Body style - 2002-2006

Updated engine to 2AZ-FE 2.4L with VVT

Coolant temp sensor connector inconsistent (2 pin vs 3 pin)

2003

Coolant temp sensor connector still inconsistent, but for this year the 2 pin meant it had an IAC and different computer logic to control it.

2004

Another year of split designs, PZEV effectively the same as 2003

Non-PZEV has an updated throttle body pinout.

All coolant temp sensors are standardized back to the 2 pin just like older cars had.

2005-2006

Throttle body pinout once again changed

Computer programming updated to require more signals to function correctly (harder to build a harness for).

 

 

 

Note: Injectors should always be matched to head and computer, fed emissions and cali emissions often times are different injectors that require different settings to work in the computer.
