How does the throttle position sensor work on a Honda Civic?
How The Throttle Position Sensor Works. Your Civic’s PCM uses several sensor inputs to control the fuel system, ignition system, and automatic transmission (to name a few). Among those sensor inputs, is the information that the throttle position sensor (TPS) provides about throttle plate angle.
Where is the throttle position sensor TPS located?
Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select Throttle position sensor TPS. A throttle position sensor signals the position of the throttle valve to the Engine Control Module (ECM). Throttle potentiometers are generally carbon track type units mounted directly onto the throttle butterfly spindle.
What are the symptoms of a bad throttle position sensor?
Symptoms Of A Bad Throttle Position Sensor (TPS) Your Honda Civic’s PCM can’t live without the input the throttle position sensor provides about throttle plate angle. So when it receives a TP signal that doesn’t square with actual engine operating conditions, your Civic is just not gonna’ run right.
How does the TPS work on a Honda Civic?
In the next subheading we’ll find out how the TPS works on your 1.6L Honda Civic. Your Civic’s PCM uses several sensor inputs to control the fuel system, ignition system, and automatic transmission (to name a few). Among those sensor inputs, is the information that the throttle position sensor (TPS) provides about throttle plate angle.

What are the DTC codes for the throttle position sensor?
TPS diagnostic trouble codes (DTC’s) stored in the vehicle’s computer’s memory. P0121: Throttle Position Sensor Performance. P0122: Throttle Position Sensor Circuit Low Voltage. P0123: Throttle Position Sensor Circuit High Voltage. Really bad gas mileage. Transmission does not shift out of second gear.

So when it receives a TP signal that doesn’t square with actual engine operating conditions, your Civic is just not gonna’ run right.
How many volts does the throttle position sensor produce?
At wide open throttle the TP sensor outputs about 4.5 Volts DC. REMEMBER: The throttle position sensor (TPS), at closed throttle, produces a low voltage signal of around 0.5 Volts DC. As the throttle plate starts to open (as you step on the accelerator pedal and accelerate the engine), this 0.5 Volt signal starts to increase.
What kind of transmission does a Honda Civic EX have?
The range-topping EX came with an impressive 1.6-liter VTEC, capable of 125-HP. Transmissions included a standard 5-speed manual, as well as a 4-speed automatic on the DX hatchback, and all sedan models. The sixth generation of the Civic was still a step forward, though, not as big a step compared to previous years.
Why does my Honda Civic not run right?
Your Honda Civic’s PCM can’t live without the input the throttle position sensor provides about throttle plate angle. So when it receives a TP signal that doesn’t square with actual engine operating conditions, your Civic is just not gonna’ run right. You’ll see one or more of the following symptoms:
Are there no lift shifts in a Honda Civic?
No lift shifts keep the turbo spooled between gear changes, for lag-free, faster shifts. It should be noted that yours truly has done no-lift shifts in the stock Civic Turbo, and it works just fine, dropping elapsed times at the drag strip.
How does the Honda Civic 1.5L turbo work?
There is a big asterisk with these quoted power figures, but for now, let’s take them at face value. Additionally, Hondata has gotten rid of the 1.5 second post-shift programmed turbo lag. This improves response, and theoretically, improves straight line acceleration. From there, the option of no-lift shift (full throttle upshifts) is offered.
When do you need to replace the throttle position sensor?
As soon as you see a mix of these throttle position sensor symptoms, you should test the TPS and if it isn’t functioning properly, it needs to be replaced. Unfortunately, a TPS cannot be repaired as it is a tiny sensor but the good news is that a new sensor “usually” isn’t too expensive so you can get back on the road soon enough.

What is the diagnostic code for bad throttle position sensor?
Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component. Diagnostic trouble codes P0120, P0121, P0122, P0123, and P0124 are what will commonly appear. The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM.
