Celica :: 1991 - Speedometer Jumping Up And Down
Feb 12, 2014
I have a 1991 Toyota Celica ST184 5SFE that has only just started to have a few issues with the Speedometer.
Issue: When driving the Speedometer may jump up and down and when taking foot off the gas it will instantly drop. Happens now and then it may work again.
I have taken the car to the mechanics and they have confirmed that the car uses a Sensor for the Speedometer.
I took my car to an Auto Electrical Mechanic and he did a few tests on the car using a tool that showed the speed of the Sensor when Driving and he has confirmed that the Sensor is working correctly as he can see the speed while driving.
He mentioned that there is likely to be an issue within the Dash and possibly a loose cable or a bad resistor.
How to troubleshoot this on the Dash and how to remove it correctly without damaging anything.

Recently I had a battery replacement and a wheel barring replaced. Once I picked up my car the speedometer started jumping. I took it back into the Sears auto place that did the work. They checked it out and then told me this was an electrical thing and that they weren't at fault. After about another day the 'check engine light' came on.
I recently moved so looked up an actual garage in TN that had good reviews and took the car in. They hooked it up to a computer and told me the speed sensor chip was bad. Since the car is a manual they said that it was ok to drive it but they wouldn't recommend that for too long while I saved money. I have seen lots of posts online about doing this yourself. I by NO means am a car person but I have seen that you can buy the speed sensor part pretty cheap online.
My questions are: Is the garage charging me an arm and a leg? Would it be a recommendation to buy the part online and then take it in to be fixed? And if so how do I know which ones are ok for my 2001 Honda accord?

So I'm having some fun issues with my S10 Blazer right now.
1992 S10 Blazer 4x4 4.3L TBI, 4-speed auto (not electronic)
ABS Codes- 41, 42, 46, 51, 52, 65, 67, 68
The speedometer is jumping around sporadically.
Gas mileage has dropped astoundingly. Tank has gotten me 80 miles!!!! Poorest MPG ever!!
Also, may be related, the tranny has shifted properly for awhile. Slips from 4th to 3rd when letting off the gas at highway speed, and won't detente shift 4th to 3rd even with the gas completely floored. I had the tranny rebuilt in November and had the detente cable replaced a couple of weeks ago. I'm going to make sure it was adjusted correctly today by using the shop manual method: shift the cable back and ratchet forward with throttle or gas pedal.
As far as the ABS and speedometer go, I'm going to test what I can with the vehicle speed sensor (VSS) and the DRAC module today. With my WinALDL scan tool, I found it is definitely not a speedometer issue because the speed coming from the computer is fluctuating as well.
There is a test in the shop manual to do, but are there any other tests for the VSS or DRAC module? Reason here is because I replaced the VSS after the tranny rebuild in November. So either the DRAC module is acting up or something in the transfer case is screwed.

I have a 1991 celica that I can not get to start. The car has the 3sfe 2.0 in it that I think came out of an 89 celica. We have put a new starter on this car, alternator, plugs, wires and distributor cap, battery and more onto this car. The car however will push start. When you turn the key everything comes on and it clicks. Nothing else happens.

I just purchased 91 Celica GT and have so far been very pleased except for one major problem. I thought Toyotas are suppose to get great gas mileage?. My car is an automatic with 150000 miles on the odometer. I'm getting around 19 mpg on the expressway. I bought this car thinking about good gas mileage. Is this normal mileage.
I've had the car tuned up (new plugs, wires, cap, etc.) I took it to my mechanic who put it on a computer and the emissions read O.K. and no code faults. I took it to a trans shop to see if the trans. was shifting O.K. and it checks out O.K.and the overdrive is working normally. I even double checked the timing to see if maybe the previous owner set the timing wrong when changing the belt. Checks out O.K.
The car seems to run and idle great with no roughness. Is this gas mileage normal and if not, how to improve it. I get better gas mileage from my 91 SUV explorer...

My cooling fan just stoped working the other day (not sure why) i replaced the fuses and relays they are all good. Now when i unhook it from the radiator fan switch it turns on but plug it back in and well it shuts off, i put a new switch to see if it will work but it started running real rough and hard to start so i put the old one back on and nothing changed. I read the book and checked everything but still nothing and why my engine light came on and it started running rough.
its a 91 celica 1.6 (4AFE)

I have a 1991 Toyota Celica GT with 220,000 on it. Will a valve job improve gas milage? I currently get about 22 mpg city driving if I use medium grade gas. The reason I ask is that I was thinking of getting a new car - but a valve job would be a lot less$$$ and I just can't see buying a new car that get less gas milage.

My sister has a 1991 toyota celica GT ITS 5spd with the 2.2L in it which is the 2200 twin cam and all that. Last week her alternater went out. I replaced it and got the correct belt tension good volts going everything but now when she is going down the road doesn't matter what gear anywhere from 1800-2800 rpms her car jerks like its missing i checked the plugs and they are white which means its starving for fuel but when its cold its no problem drives perfect i was thinking replacing new plugs new wire distributor cap and fuel filter and seeing if that solves it...

I have been trying everything to get my speedo working on my Ford. It didn't work for 3 months after I got it then I decided to put some gear oil on the cable. This made it work for about 200 miles then it would only work with the clutch in and then not at all. I've replaced the speed sensor(not one on rear end the thing the cable goes into), and the gear that goes on the end of it. If I hook a drill up to the cable the tach moves. Could the cable be stretched or just needs some speedo cable lube?

Its a 1991 Toyota celica with the 1.6 and 5 speed trans. the motor on cold or hot start up shakes really bad and has a lot of valve chatter. Along with that, the motor does not want to rev at all, almost like you are not even touching the gas, but you have it to the floor. A little back ground on the car is, the car sat for 6 months and i bought it from a friend to drive back and forth to work to keep miles of my supra. He said that the CAT was plugged so i replaced it. I have replaced the coil pack, distro cap, spark plug wires, spark plugs, rotor button, catalytic converter, air intake, and all the air tubes that looked like they were cracking. Now I can start the car, and it does the same thing. I thought it may be out of time, just because that is sort of what its acting like. I have had the motor rev up 3 times since i have had the car. But everytime I do it back fires and DIES, the car will not start til after the car cools down.

while out of town the big belt that runs the alternater and ac broke and took out the power steering belt. I replaced the big belt but do not know how to do the power steering one. I can hardly see the back sprocket.

I have a 1991 celica gt 5sfe hatchback. I am getting a surging at constant speed, at idle it's fine as well as acceleration. It only does it when trying to maintain a constant speed in the range of 10-50 mph or so. It's feels like I'm pushing the gas and letting off repeatedly. I took it to get an emissions test and it failed on the low side test with high co2 reading, everything else is fine and one place couldn't do the test because the surging kept kicking the computer out since they have to keep it at a constant 15 mph speed. I think whatever is causing the surging is causing me to fail the low side emissions. Could it be the iecu?

This is on a '91 Celica GT, 5SFE engine, with front disks and rear drums, and no ABS.
Whenever braking, the front passenger wheel seems to be doing much more of the braking work. In the wet, its very easy to lock up the front pass wheel under pretty mild braking. In the dry the same wheel is always the first to lock up, considerably before the drivers front, and much before they should, based on the deceleration.
I recently had to replace all the brake hoses, and a long run of hard brake line from the engine compartment back to the gas tank. I've bled the system multiple times and doublechecked all the connections, and cannot find any leaks. With no brakes applied, all wheels spin freely.
It seems like the braking circuit for the driver front wheel is not working as well as it should be. Is the passenger rear brake on the same circuit as the driver front? This seems like air still in the lines somewhere.
Could the master cylinder be causing distribution problems between the two circuits?

I have a 1991 740 Wagon with ~153,000 miles. I say approximately, because the speedometer, the odometer, and cruise control stopped working. My mechanic says it is the sensor loctated on the differential, I believe he said.
2 questions: My local Volvo junkyard has gone out of business; where is a good place online to get used parts? and second, .is sensor difficult to replace? I can fix things that are easy.

It acts like it is fuel poor, As if the fuel pump is not pumping. It spins fast on start. Then another try and it starts! No relationship to hot or cold. Fuel OK. Battery strong. I find no corrosion on fuel pump leads.
