There is a possibility the new module is faulty, but there may be something else going on with the car as well. Wiring can be an issue with these vehicle so consider hiring an experienced technician like one from YourMechanic to loo at the car and offer a personal diagnosis. You can have bad knock sensors offering false readings or some faulted wiring.

Common signs include lacking power when accelerating, rough or slow idle, stalling, inability to shift up, and the Check Engine Light coming on.
Without a throttle position sensor, the engine control module wouldn`t be able to accurately time the ignition or monitor the amount of fuel required, which might cause the engine to surge or stall and be exceedingly dangerous for the driver and other road/track users.
Do you have to reset computer after replacing throttle position sensor? After replacing the throttle position sensor in your engine, if the engine light was on and has a pending code, the code should go away. If the code doesn`t, however, then the ECM (engine computer module) will need resetting.
A P0122 code is the generic OBD-II code defined as “Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input.” This code relates to the vehicle`s Engine Control Module (ECM) and TPS Sensor Circuit A output voltage and is triggered when the voltage falls below the sensor`s anticipated range.
A malfunctioning TPS will cause your engine to run poorly. Generally the engine will idle fine but will have difficulty accelerating. This is because the computer isn`t telling the engine to inject as much fuel as is required, while at the same time airflow is increasing.
The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.
Within a motorsport engine – or the engine of any vehicle, there is a throttle valve. The throttle valve opens when the accelerator pedal is compressed. A throttle position sensor is used to measure how open the throttle valve is and therefore controls the amount of air which can flow into the engines intake manifold.
With the vehicle off, turn the key to the “On” position, but do not start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh.
What happens when you reset an ECU? By resetting the Engine Control Module, you can return your car to its factory settings. This will erase any error codes or radio stations that were stored in the car`s memory.
It will eventually learn on its own, but it may take several days to a week of driving. In this time, the engine may experience high and low idle speeds, and possibly rough idle. The following is an example of a throttle body relearn procedure from GM: Start the engine and let it idle for three minutes in park.
Step 1: After you finish cleaning your throttle body, start the car and let it idle for four minutes. The RPMs might be high at first but should gradually settle down as the ECU absorbs the data. Step 2: Turn off the car for 90 seconds. Then, turn it back on and allow it to idle for another four minutes.
In fact, on some engines a new throttle body needs to be programmed with a factory, or equivalent, scan tool. The technician cannot even clean the carbon out of the throttle body in some cases without setting a “check engine” light.
Check engine light
The check engine light can indicate many issues within a car including a faulty throttle body. In more modern cars, an electronic throttle control (ETC) constantly monitors throttle body performance. Any problem detected with it will turn on the check engine light.
One is a vacuum leak due to a failed intake manifold or throttle body gasket. This will cause a major vacuum leak and trigger a lean condition.
When a throttle body is not functioning correctly, you`ll usually notice a distinctly poor or very low idle. If the problem is really severe, you might even begin stalling when coming to a stop or when the throttle is quickly pressed.
Because the TP sensor is an input to the control module for various automatic transmission functions (e.g., shift points and torque converter clutch operation), a problem with the sensor can cause transmission performance issues. For example, you might experience harsh or delayed shifting.
The TPS adjustment is very touchy so make sure that you make small adjustments. If the TPS fails to read the proper resistance in any tests then it should be replaced.
The accelerator pedal sensor (APS) indicates the position of the accelerator on vehicle models with electronic throttle control. The APS is basically a throttle position sensor (TPS) with a pedal attached.
With the L98 5.7-liter engine, acceleration to 60 mph takes 6.6 seconds, and the quarter-mile marker rushes past in 14.8 sec at 96.5 mph.
Overview. The 5.7L LS6 debuted in the 2001 Chevrolet Corvette Z06 as a high-performance variant of the LS1 engine found in the standard Corvette C5.
The Chevrolet Corvette C5 5.7 344 PS claimed weight (DIN) is 1472 kg / 3245 lb. What is the claimed top speed of a Chevrolet Corvette C5 5.7 344 PS? The Chevrolet Corvette C5 5.7 344 PS claimed top speed is 277 km/h / 172 mph.
The big news for 1989 was the completely new six speed manual transmission. It was designed for the Corvette by Zahnradfabrik Friedrichshafen A.G. (ZF) a German transmission builder with an excellent background for producing bulletproof transmissions for high horsepower applications.
The 1989 Chevrolet Corvette was the first to offer a 6-speed manual transmission, taking the place of the 4+3 transmission that had appeared in the other C4 cars. The base engine was a 5.7-liter L98 350-ci V8 rated at 240 horsepower. $25,895 would get you the Callaway option and an increase to 382 horsepower.
The Chevrolet Corvette (C4) is the fourth generation of the Corvette sports car, produced by American automobile manufacturer Chevrolet from 1983 until 1996.
