Top 10 1994 Toyota Camry Questions & Answers

I had the same problem recently but replacing the ignition Coil under the distributor (inside) solved the problem. Also replaced the distributor Cap and rotor at the same time.

Hi.....

The Normal Temperature Range to the Fan Start is: A/C ON 181 F.
A/C OFF 199 F. When the Engine Reach this Temperature the Fan should start.

OK. Do this simple test.
1---- Start the engine, Desconnect the ECT Switch located on the Radiator,
See if the Fan come ON. If yes, if not go to step #2
Connect the ECT SWITCH and leave the car Running and with a Temperature gage.
See the temperature, if the Temperature go more than 199 F.
Turn the Engine OFF.
Disconnect the ECT sensor and check for Ground at the WHITE/BLACK wire.
If ground exist, Replace the ECT switch.
But if not. Check the wire for any damaged, and the ground at the Front Left Fender.
Repair as need.

2---- check the Fuse link RDI FAN . 30 amp.
Check the Fuse link CDS FAN 30 amp.
Replace if need.
And Return to step # 1.
Check the Radiator fan Relay, Rad fan relay 2 and 3. Replace if need.

Ok. I hope this help on your question.
I can give to you the WIRING DIAGRAM of the Fans, But I need a E-MAIL adress to do that.

Thank you for use fixya....

well it didn't hurt anything to put the new fluids in. Always good to keep up on those some of the time forgotten routine maintenance. The erratic idle could be caused by a number of things. A leaking intake manifold gasket is one but usually is a steady higher racing idle. Could be clogged injector/s, not sure if you have a throttle body which would house a single injector or a fuel rail which would house 4, one by each cylinder. The other possibilities are any of the sensors that feed the information needed to the brain/on board computer to control the air and fuel to the engine under all conditions for optimal performance, and the emission control system.
Trouble shooting comes with several options. Fortunately most vehicles since the start of the electronic fuel injection systems, that would be everything since the end of the carburetor, comes with some description of an on board diagnostic system for trouble shooting the sensors and such.You can purchase a diagnostic tool, and you will need to purchase a Haynes or Chiltons Manual for your year make and model which will tell you what all of the different codes mean. You can find these at any of the auto part chains such as Auto Zone, Discount Auto Parts, Pep Boys etc. Most of these stores will test your on board diagnostics with their tool free of charge. The Manual never hurts to have in your possession as it covers mostly everything from A to Z for mechanical and electrical repair and troubleshooting. Some vehicles have a way of giving you error msg's by a series of turning the ignition key on and off a certain number of times, and giving a code by a series of an in dash light blinking and pausing, this would also be covered in the manual for your make and model.
Hope this helps,

Cigarette/radio is a 15amp fuse located in the panel, middle row, bottom fuse. Basically you have 3 colums and 4 rows of fuses in there.

the switch where you turn it to blowing at your head is probably out. you will need to replace the switch control where your defrost, foot, head etc. what make, model, year is your vehicle?

1994 Toyota Camry 2.2L EFI DOHC 4cyl
On both diesel and gasoline engines, the thermostat is located in the water inlet housing connected to the lower radiator hose.

R
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
Gasoline Engines
(see Figures 1, 2, 3, 4, 5, 6 and 7)

1. Position a suitable drain pan under the radiator drain **** and drain the cooling system.
2. On the 1MZ-FE engine, remove the air cleaner cap assembly. Be sure to label all wiring disconnected.
3. Disconnect the water temperature switch harness from the water inlet housing (except 5S-FE engines).
4. Remove the oil filter on 5S-FE engines. On the 1MZ-FE engines, remove the heater hose covering the housing.
5. Loosen the hose clamp and disconnect the lower radiator hose from the water inlet housing.
6. Remove the two nuts from the water inlet housing and remove the housing from the water pump studs.
7. Remove the thermostat and rubber O-ring gasket from the water inlet housing.

To install:

1. Make sure all the gasket surfaces are clean. Clean the inside of the inlet housing and the radiator hose connection with a rag.
2. Install the new rubber O-ring gasket onto the thermostat. On 2SE and 3S-FE engines, align the jiggle valve of the thermostat with the protrusion on the water inlet housing. On 5S-FE engines, align the jiggle valve with the upper side of the stud bolt. On 2VZ-FE and 3VZ-FE engines, align the jiggle valve with the stud bolt. Insert the thermostat into the housing.

1. Position the water inlet housing with the thermostat over the studs on the water pump and install the two nuts. Tighten the two nuts to 78 inch lbs. (9 Nm) on 4 cyl. engines, 2VZ-FE and 3VZ-FE; 14 ft. lbs. (20 Nm) and 69 inch lbs. (8 Nm) on 1MZ-FE engines.

Don't forget to install a new O-ring onto the water inlet pipe. Apply soapy water to the O-ring prior to installation.

1. Connect the lower radiator hose to the inlet housing and install the hose clamp. On the 3VZ-FE, tighten the bolt holding the water inlet hose to the alternator belt adjusting bar to 14 ft. lbs. (20 Nm). On the 1MZ-FE engine, tighten the bolt retaining the water inlet pipe to the cylinder head to 14 ft. lbs. (20 Nm).
2. Attach the water temperature switch connector.
3. On the 1MZ-FE engines, install the heater hose removed.
4. Install the oil filter and check the oil level if removed. Install the air cleaner cap assembly on the 1MZ-FE engines.
5. Fill the cooling system with a good brand of ethylene glycol based coolant.
6. Start the engine and inspect for leaks.

Hello, and welcome to FIxYa.

To erase the check engine light on a 1994 Camry, open the hood, and, in the engine compartment fuse box, remove the blue 15 amp EFI fuse for one minute. This will clear the codes. If you have a hard code; ie a malfunctioning sensor, the light will come right back on.

Thanks for choosing FixYa for assistance.

I hope helps (remember to rate this).

Hi, according to autozone.com, the connector is under hood, driver side, side of strut tower, mounted on strut tower. The pic below, hoewever shows it mounted to the intake manifold. This is an OBD1 connector. You must use an OBD1 scanner to extract trouble codes or use the manual procedure pasted below. Please let me know if you need an explanation of the trouble codes (please specify your engine and trouble code) or have any other questions.



All models except the 1MZ-FE engine is equipped with OBD I till 1995.

1. Make sure the battery voltage is at least 11 volts.
2. Make sure the throttle valve is fully closed.
3. Place the gear shift lever in Neutral. Turn all accessories off.
4. The engine should be at normal operating temperature.
5. Using a jumper wire, connect terminals TE1 and E1 of the Data Link Connector 1 (DLC1).
6. Turn the ignition switch ON , but do not start the engine. Read the diagnostic code by the counting the number of flashes of the malfunction indicator lamp.
7. Codes will flash in numerical order. If no faults are stored, the lamp flashes continuously every 1 / 2 second. This is sometimes called the Normal or System Clear signal.
8. After the diagnosis check, turn the ignition OFF and remove the jumper wire.
9. Compare the codes found to the applicable diagnostic code chart. If necessary, refer to the individual component tests in this section. If the component tests are OK, test the wire harness and connectors for shorts, opens and poor connections.
