2002 Camry xle won't accelerate
I recently had to jump my 2002 xle battery unawares I put the jumper cable on wrong and drained the battery, I fixed the cables and got the engine running but the accelerator will not work a coder told me the throttle body circuit malfunctioned so I got a new throttle body and the accelerator still won't work any suggestion?
|
What was the code?
Check ECTS fuse located in a fuse box in the engine compartment. |
I don't know exactly what number the code was but the mechanic told me that it read throttle body circuit malfunction
|
Check fuse.
The throttle circuit also include the throttle pedal sender. |
Thanks I had a mechanic who read that and changed the throttle body and didn't realize that it could be the pedal sensor until afterward, I had it towed to a shop tonight I will see what they say this probably the issue. Do you by any chance now the price of labor for changing this fuse?
|
The fuse and throttle pedal sensor are two different items.
Fuse replacement is very easy, a 5 minute job. Fuses are low cost ($1). The throttle pedal sensor is more involved and more expensive. |
Oh ok so I would be able to change the fuse myself, the shop that I took my car to will not open again until tomorrow morning I'm thinking that the problem may be the pedal sensor since the first person I took it to said that he changed all the bad fuses.
|
Great. Please post back with the findings of the shop.
|
So check it out, there was a light on in my trunk that would stay on because my trunk is tied down and not latched this light drained my battery so much that it caused the pedal sensor to malfunction. They put a new battery in problem solved 88 dollars. My only question now is did I really need a throttle body? And how do I know if a throttle body has gone bad?
|
The throttle now operates normally, if so operate car as is.
The dead battery could have caused issues as the throttle is electric. The throttle system is connected to the engine computer that interacts with its operation. A dead battery can cause the computer to need to reset or relearn. As to throttle body, when the throttle electric motor fails the throttle goes to limp home setting or minimal throttle to be able to get off the road. Motor failure is not uncommon. In your situation the throttle worked normally before the battery problem. In this case best not to assume more then just a battery problem causing other problems. The throttle system fuse as noted can also blow. Diagnosing the system requires service manual info. However one quick check for operation is to turn ign switch to ON and have someone operate the throttle while listening for smooth operation of the throttle motor. |
Ok cool so I'll just assume it was the battery since this didn't start until the battery went out, the thing is I think I spent 300 dollars on a used throttle body that I might not have had to replace, the mechanic showed me my old TB that was cracked at the top but I still don't know if I needed to replace it.
|
Appears so if the shop only replaced the battery.
Keep the old TB as a spare as they do fail. |
Ok so I'll assume that the battery was the problem, the frustrating thing though is wasting 300 buck on a throttle body I probably didn't need but lesson learned.
|
Appears so if all that was done was to replace the battery.
Disconnecting the battery can cause strange problems that can work themselves out. In your case the battery went dead. What these problems are has not been documented. The shop manual has no info on problems related to lack of battery power. Thus can't assume the problem is related to the lack of battery power. Throttle motor failure is very common requiring throttle body replacement. As such replacing it was not without cause. Suggest retaining the old throttle body as may need it in the future and new throttle bodies are very expensive. If the crack doesn't effect operation may be able to sell it on Ebay as this is common. The engine computer interfaces between the throttle motor and gas pedal sender. Gas pedal inputs are not a one to one correlation with the throttle motor operation. The computer modifies the signal based on software and gas pedal inputs over time. If the battery power is lost, the computer can need to relearn again. For future reference might pickup a Haynes service manual or other service info to be able to run specific tests on the throttle system. |

The gear would once more become forceful when changing the third gear and then the engine will stall and won't Rev or accelerate unless I stop and start the car all over again. Please how do I fix this problem? |
I noticed my car would forcefully engage when entering the third gear, and it would trigger the engine to stop revving and accelerating until I kill the engine and start it up again.
I visited an auto shop and had a diagnosis. I have changed the throttle sensor, the throttle body and the gearbox as well, yet I still notice that it engages the third gear forcefully occasionally and do still trigger my car to stop revving and accelerating. Please what do I do? I need urgent help please! |
Describe forcefully as in HARSH shifting.
The trans slams into 3rd gear and then the engine dies? How does this happen? You foot is on the gas pedal, the trans shifts (bam), your foot is still on the pedal and the engine quits? Is it possible the trans no longer being engaged in 3rd, the engine revs up then you take your foot off the pedal and the engine RPM drops to idle then dies? Did you have the transmission replaced or repaired or what? Was the torque converter replaced? Did you have the checked by a Toyota dealer or a competent trans shop? You state once in third gear there is no engine drive power and you need to coast to a stop to reengage the power? The transmission is shifted via a computer which has software. This software at times is updated to solve issues. But don't think this is the problem Harsh shifting might be caused by a throttle position sensor but you state the trans also drops out of third gear. Dropping out of gear is another issue beyond an engine problem. Without further info guessing???? a torque converter issue. The converter disconnects from the transmission in third. But just a guess. Your problem does happen as seen it on other cars. No power in high gear-needing to coast to a stop to reengage trans. A COMPETENT trans shop would be able to disgnosis the problem. |
Yes! It HARSH shifts into the third gear and with my feet on the gas the engine will die and stop accelerating.
Sometimes even after I killed the engine and restart it will keep idling for a while. I will restart about 3 times before the engine will rev again. I changed both gearbox and torque converter. At times it runs smoothly, and the gear selection is smooth...at other times it begins to do HARSH selection and the problem continues. Most especially when I want to accelerate quickly! |
Might be the trans software. This is supposed to determine shifting time.
|
Alright, I'll get it changed and hope it fixes the problem.

My 2002 CAMRY doesn't run smoothly
My Camry does not run smoothly.
It is worse when I have to put on the air conditioning. Once I put on the air-conditioning, it will drag to accelerate and eventually kill the engine completely. I would have to turn off AC and restart the car. How can I repair it? |
What have done to try to fix the problem?
|
I have taken it for repairs and after scan the fuel pump and fuel filters were changed, throttle body and throttle pedal sensor was changed too, Three coils were changed and the plugs were changed too. I also got a new battery.
The fuses were checked and some were replaced...Yet the problem persists. |
Did you change the emissions converter?
|
No. I haven't changed that.
