What causes a bad TPS on a Honda Accord?
The throttle position sensor (TPS) on your Accord controls many aspects of the car’s engine performance. Symptoms of a bad TPS include rough idling, bouncing RPMs upon deceleration, or a lurch/lag response upon acceleration. Unfortunately, many folks are lead to believe that bad gas or clogged injectors are to blame,…
What should I do if my throttle position sensor fails?
This is intended to at least allow a driver to get off a busy highway in a safer manner. Once the TPS begins to fail, even partially, you’ll need to replace it right away. Replacing the TPS will include clearing relevant fault codes, and may require software reprogramming of the new TPS module to match other engine management software.
What’s the correct voltage for a Honda TPS?
The correct voltage of the new TPS is .5 volts with no throttle and 4.5 volts with the throttle wide open. The Brown/Red wire (center wire) from the connector is what sends the voltage to the D11 position of the Engine Control Unit (ECU), telling it if the throttle is open or closed. This wire connects to the center pin of the TPS.

Can a bad throttle sensor be replaced on a Honda Civic?
Honda has not made it easy to replace only a bad throttle position sensor, instead choosing to fasten it down with semi-permanent screws in many older models. While many people will simply replace the entire throttle body, this is obviously not necessary.
What’s the best way to turbocharge a Honda Accord?
The larger cone filter on the intake side delivers denser, colder air to the engine for better throttle response and a slight gain in horsepower. Supercharge or turbocharge the engine. While this is the most expensive option for making an Accord faster (at least in a straight line), it is also one of the most effective.
What kind of transmission does a Honda Accord have?
In the U.S. market, the sedan was available in two colors: silver with maroon cloth interior or dark red with maroon cloth interior. In 1980 the optional two-speed semi-automatic transmission of previous years became a three-speed fully automatic gearbox (a four-speed automatic transaxle was not used in the Accord until the 1983 model year).
Can a Honda throttle body be cleaned and reset?
This article pertains to Honda throttle body cleaning and a Honda throttle body reset. All electronic throttle bodies accumulate carbon buildup on the throttle plate and bore—the Honda throttle body is no exception.
Why did Honda change the throttle body for fuel injection?
When carmakers switched to fuel injection, the purpose of the throttle body change to operate more like an air valve, allowing more air into the intak manifold as you put the pedal to the metal. To provide air at idle, carmakers installed an idle air bypass valve that allowed air to flow around the closed throttle plate.
What should the TPS be on a Honda Accord?
If your Accord is showing those signs, an easy way to test your TPS is to use a voltmeter to read the output when the throttle is pressed and released. The TPS should show .5 volts with no throttle and 4.5 with the throttle wide open.
What is OBDII code for Honda Accord p0122?
P0122 is a common trouble code with the Honda Accord. It’s an OBDII code that references issues with the Throttle Position Sensor (TPS). It is relatively serious problem since it can leave your vehicle stranded or severely limited. OBDII code P0122 is a serious problem that requires serious attention.
The correct voltage of the new TPS is .5 volts with no throttle and 4.5 volts with the throttle wide open.

What are the symptoms of a bad TPS?
Symptoms of a bad TPS include rough idling, bouncing RPMs upon deceleration, or a lurch/lag response upon acceleration. Unfortunately, many folks are lead to believe that bad gas or clogged injectors are to blame, only to find that the problem still exists after fixing those “causes.”.
How to change throttle position on Honda Accord?
Install the new TPS, but leave the bolts loose enough that the TPS can be turned. Plug in the electrical connector, then back-probe the middle wire on the connector with a paper clip or similar. Attach the red lead from a multimeter to the paper lip with an alligator clip. Ground the black multimeter lead to the battery ground.
What to do if Honda Accord TPMS light on?
Honda owners, rejoice! There is a widely reported solution: tell your Honda-certified mechanic about your problem and ask them to perform the software upgrade outlined in TSB #14-006. We are looking for a copy of this document, but from all accounts it a simple software upgrade that fixes many TPMS problems:
