Question about 1997 Toyota Corolla

1 Answer

Car doesn't start when ambient temperature is over 80 degrees

Car starts only when it's cool outside. Battery and alternator seem to check out alright. Is this maybe some kind of electrical ground problem or selanoid issue? Thanks. Appreciate any input.

Dear yshrek39,
if the ones you mentioned are ok, try on having your ignition coil tested.

06 rendezvous that the digital temp display for outside temp is wrong. The display reads 32 degree and it is actually 80 degrees so the A/C does not cool vehicle down. What is the problem?

Suspect a failure in the ambient air temp sensor. Has the vehicle ever been in a frontal collision? This sensor is normally located in front of the radiator assembly bolted to the rad support. If it is reading a cold temperature, it will not allow the AC to operate

No start cold

temp sensor failed. could be the air intake sensor... or the ecu temp sensor falling... easy to find out if intake sensor failing. before starting on a cold morning. or under 10 degrees.. unhook the air pipe and blow with your breath over the sensor put back and start engine. if engine starts fine then that's your problem.

AC recirculation is not working (outside temp is -37 degree centiigrade).

there is a damper that opens and closes to allow air to recirculate or come from outside. Find out where that is and check it out.

When the car is at operating temperature and the outside temperature is hot the car will not start

The car is obviously itself running at an above average tempareture thus adding to the effect of the outside tempareture having an influence because their is not enough cool air outside to cool down the engine fast enough and probably one or two electronic components are being affected by the intense heat as heat is a major problem in all electronic components causing them to break down, especially within a hot engine compartment of a motor vehicle.Contraction and expansion is what causes the fluctuation within the component's performance.This could very likely be an erratic electronic contact, and in the event of a carburettor model could also be a hot mechanical fuel pump. Try pouring water at a slow rate over the various components like the electronic module, some of the sensors on the engine, Hold a cool wet rag over the airflow meter, and place a cool wet rag around the distributor, the coil, etc.Sometimes even a hot relay switch can be a headache.As you go along try starting the car again after each cooling session on the various components and you will eventually find out which one is the problem. Good luck.

No start due low ambient tempreture

When you say it wont turn over you mean you turn the key and nothing happens, or the engine cranks and just wont start?

My outdoor air temp. reads -56 degrees when starting car, real air temp is 80, it keeps the a/c from turning on.

Hello, this is usually caused by a bad outside air temp sensor. the sensor is mounted behind the front grill, it has one connector with two wires pluged into it.
here is a picture of the sensor

Air conditioner comes on briefly then stops. The temperature gage on the panel which shows outside temperature is inaccurate sometimes giving a display of -27 degrees.

Well the outside temperature gauge is generally not wired into the a/c. The internal temperature is more important but is not displayed as such. The 'internal' temperature sensor is used to regulate the a/c blending door and blower speed.

When did the cooling problem start?

Need to know coolant temp operating range for 1988 Seville

Entirely possible and in range. Depends on outside temps and type of driving. The radiator is colled by electric cooling fans, controlled by temp sensors. Fans should come on automatically when a/c is turned on

Onboard temp gauge

you need to go to the parts house and purchase an ambient temperature sensor. that is the sensor that tells the car what the outside temp. is. I hope that helps you out.

The ambient temperature sensor going bad causes this exact problem. I've replaced many of them because when they show outside temp as being below 60 degrees, the A/C control module will shut the compressor off.
