While driving on the highway, I experienced an issue with the vehicle's performance under moderate acceleration (approximately 3000 RPM). The engine will no longer output power that is proportional to the amount I am requesting with the gas pedal. Once the issue occurs, the maximum power output is only 2000 RPM with the gas pedal fully pressed. The issue is occasionally resolved by shutting the engine off and waiting a few moments. The check engine light comes on with the code po120. The code translates to a faulty throttle position sensor but toyota will not replace the $60 sensor individually, they will only replace the $1,200 throttle body that includes a new sensor.

Car stumbles/hesitates intermittently at various speeds. Have spent time/money trouble shooting the problem/making repairs with no affect on problem. Problem appears to be drive by wire throttle body toyota part # 22030-62020 (toyota data per VIN shows this part should not be on my car). Toyota has a program to replace throttle body if found to be defective (for a limited time) except problem cannot be duplicated in the shop and it does not cause any codes. On-line research indicated problem is with the throttle position sensor (tsp) or the accelerator pedal position sensor (apps) on the throttle body failing. Research indicates toyota is aware of this problem as they will replace part free if proven defective and apparently has redesigned their throttle body. Issue is, most of the time the dealer cannot reproduce the problem in the shop and since it does not cause a code they will not honor the warranty program because they will not be reimbursed without proving the part is defective. The problem with this throttle body has been identified in vehicles with as little as 30000 miles to over 250000 miles per on-line research. While riding with me the dealer's technician has seen and felt the stumble/hesitation (RPM drops about 150 to 250 RPM when traveling at a constant speed for no reason) but has never been able to duplicate it in the shop or identify the cause. This stumbling/hesitation occurs everytime the car has been driven for longer than 20-30 minutes since the 1st occurrence. Twice it has stumble while making a left turn at an intersection causing me to almost get hit by an on coming vehicle. This throttle body is a non-serviceable part and cannot be repaired, per the dealer it is required to be replaced as a unit. This part needs to be recalled and toyota required to replace it at no cost now instead of only when it fails before someone is killed.

While driving in traffic the throttle stuck at above normal idle and the check engine light came on. I was able to exit the traffic but the idle would not come back to normal curb idle. What my mechanic has told me is that the throttle body assembly has failed and they can only get the part from the dealer. If this had happened on the freeway the outcome could have not been so good. I hope toyota is aware of this problem and going to address the situation.

The problem that exists is on my 2003 toyota tacoma. It will all of a sudden lose power and have no throttle response, almost as if it was hitting an engine governor. The rpms usually drop anywhere from 200-500 and then comes back up. The power would slowly come back after keeping my foot on the throttle. It consistently does it after accelerating out of an intersection (usually around 25 MPH or while cruising (around both 45 MPH or 75 MPH) on the highway. This drop of power or lack thereof is a huge safety issue, especially when pulling into an intersection or needing quick acceleration to avoid an accident. I have read about many others with the same issues with their late model tacomas. The parts to fix the issue are very costly and the problem seems to be widespread. [xxx] request research.

I'm filing the compliant to acknowledge the fact that these older fly by wire throttle bodies have a faulty tps that is only replaceable as a whole new throttle body. The cost on them is between 700 to 1000 dollars. My tacoma do have a faulty tps on it. I'm waiting to save up enough money to replace the throttle body however, there have been numerous times that upon pulling out into traffic it has acted up. When this happens you get a very bad hesitation or lack of acceleration to the point of endangering myself and other drivers. The hesitation has lasted as long as 3 to 5 seconds before the throttle will finally respond. The condition will only happen during hot summer months. Thank you for your time and would like the see this looked into and or resolved. I will be able to replace the throttle body because I work at a dealership and get the parts at cost. However some people may not be able to save up the cost for the new part. Thanks again sincerely!!

Cover for gas tank totally rotted out and tank is exposed. This vehicle has recall 9355 - emergency spare tire. Not sure why this isn't also covered. Looks unsafe to me.
