Question about Cars & Trucks

2 Answers

Hi. I have 2003 Toyota Sequoia. I just replaced a dead battery with a brand new one. When connected the new battery, it started blowing horn so I did handle that with pressing the unlock key on key FOB and it worked. My car starts and can stay on at 1000-1250 rpm however, nothing is happening when I push the gas paddle. I went even on drive and it just drives at 15 miles speed and at the 1000-1500 rpm. After driving 5 miles like that it went up to 25 miles speed and 1500-2000 rpm. However when I push the gas paddle NO response and the car runs by itself and even when I pushing the gas paddle it doesn't pick up any more speed nor responds or accelerate. Bottom line, NO response from engine when I push the gas paddle. Any idea how to resolve this issue?

When the battery is removed from the system there is a possibility of program corruption in the CPU . After battery work it is always a good idea to reset the CPU with a code reader. Try that first and then read for any fault codes and go from there.

Sounds like your car is in the limp home mode. When the computer in your car fails it goes into a limp home mode that lets you drive it home at a slow speed. Sounds like when you changed the battery you may have damaged the computer. Take it to the dealer to have it checked out.

SOURCE: Check Engine light and ESC OFF light

I had an issue where the ABS and ESC lights would go on and wouldn't turn off unless I restarted the car (sometimes they would light up again even if I had restarted). This was because the speed sensor was broken on my back tire. After the dealership replaced it, (under the 36,000 mile warranty) all was good and I have yet to see the lights come back on.

Summary:
Issue: ABS & ESC would not turn off
Solution: Replaced broken speed sensor on tire

i have a 2003 sequoia ltd and i can tell you that the virtual traction control lights will come on after ignition and remain on as a result of anything that has affected your vehicle operation. from sensors to seals, the computer is designed to shut down the traction control if it has determined that any part of the engine/mechanical systems has malfunctioned. first it was the abs had to be reset after i slammed my brakes on. next i needed a new fuel/oxygen sensor, the passenger primary, and after having fixed both the traction control operates properly, lights go off after ignition and stay off. i think the vehicle operates more driver friendly when its off, because it doesn't go off every time one of the wheels slips. i expect it will happen next time something else malfunctions, its toyotas way of annoying you into their service shop. go to a tune-up shop, (minitune) instead they'll tell you whats wrong and it'll be cheaper.

SOURCE: grinding noise while driving.

Possible causes:

a) a brake disc shield is too close to the disc, and it's coming into contact in the circumstances you outline

b) pebbles stuck between the disc shield and the disk

c) dried out wheel bearings

d) worn Universal Joints in the drive shafts

e) worn A/C pump

f) worn alternator

g) worn water pump

Is the noise still present above 15 miles an hour and past 1500 rpm when the clutch is disengaged (i.e. gearbox in neutral?). The answer to this question may help you to pinpoint the source. I know it's stating the obvious but the fact that you're hearing a grinding sound means it's caused by something that is moving relative to something else. Again this should help narrow down the cause.

SOURCE: key fob lights up but doesn't work even with a new battery

I'm more familiar with Range Rovers and Saab's when it comes to key fobs but if you changed the battery you have to re-program the key fob. If you do not have an owner's manual that can take you through the steps you might want to try: push and hold the lock button on the key fob, put it in the driver's side door and turn to lock. With the button still depressed turn back to open, remove the key and release the button. If this doesn't work check any and all fuses associated with your system and last but not least you could take it to a dealer. Good luck!

On some models you can disable the alarm after you connect the battery by locking and unlocking the driver door with the key.
I would disconnect the horn or pull the relay until you can get the alarm turned off.

The horn on my sequoia randomly went off,no one was driving it it was just parked in the drive way. I had to unplug the horn.


Could be a motion sensor is going bad (sensors that detect someone breaking in). See if you dealer can verify they are OK.

2003 Toyota Sequoia won't start.


Have you gotten this problem fixed yet? If not what is the condition of the battery cables( corrosion free)? Also how old is the battery? One dead cell could possibly cause this problem.
