20 Most Recent 1997 Toyota T100 Questions & Answers

I bet you will get a code P0113 if you scan it.

The resistance at the MAF sensor should be lower than 16k ohms between the A and F terminal. If it is, then the sensor is ok. Measure voltage at the F terminal (harness) should be 5V. If all is ok it MAY need a pcm, but I would have a professional shop checkk it first.

My Toyota had the same code and the problem was that the Throttle body was gummed up after 182,000 miles of use and wasn't allowing enough vacuum to trip the MAF sensor thus causing the code.

Take off the throttle body and clean it up and the code will disappear. At least it did for me.

Also you can read this:-

There can be a misfire too from the cylinders.

An engine that hesitates, stumbles or misfires when accelerating or when it is under load is an engine that is either sucking too much air, not getting enough fuel or misfiring. If the Check Engine Light comes on, you may find any of the following codes:

• P0171, P0174 Lean fuel condition codes
• P0120 to P0124 Throttle position sensor codes
• P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR related codes

If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.

Another common cause is dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your scantool. If the numbers are high, it tells you the engine is running lean and the injectors need cleaning. Treat mild cases with a high quality fuel-injector cleaner additive. Severe cases require professional cleaning equipment.

Good luck and thanks for using Fixya.

No spark?

run the fault codes could be a fuel pressure problem or injectors leaking and causing it to flood

Most likely the fuel pump is failing, the fuel pressure check valve is defective and the system loses pressure the long crank is due to this loss of fuel system pressure.

The problem is not the parts but the communication between the parts and the computer. I would have the computer reflash and then drive the vehicle for a extended amount of time. This should fix the problem.

Could be a blown head gasket. You might also need to "burp" the system. When the vehicle is completely cooled down, try taking the radiator cap off, topping off fluid, and start the engine. That should help get air out. If it starts bubbling and shooting coolant out, something is wrong. You could also try running without the thermostat or just go ahead and replace it. They aren't usually expensive.

I have had many shops attempt to work on toyotas. even some toyota dealers can not fix older toyotas. best thing to do is find a shop that is specializes in toyotas and Japanese vehicles. sometimes they cost more but they fix the problem.

Bad dimmer switch.

no --- there is a wall between the two so that if one line blows then the fluid is not lost to the other brakes

Did you check the dimmer switch for power ?

drain plug is at bottom of tranny, the fill hole is on the side of tranny about half way up from the bottom of tranny. I think they are about 22mm in size or 7/8".

Hi Michael, You really need a good workshopmanual. Haynes is about the best. l Haynes is the information resource for the DIY enthusiast

Yes me too l suject you to check for vacuum leak

Start with the battery.
