Code P1223 Description
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM). In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
What are the Possible Causes of the DTC P1223?
- Faulty Electric throttle control actuator (TP sensor 2)
- Electric throttle control actuator (TP sensor 2) harness is open or shorted
- Electric throttle control actuator (TP sensor 2) circuit poor electrical connection
How to Fix the DTC P1223?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0
To diagnose the P1223 code, it typically requires 1.0 hour of labor. Rates vary by location, vehicle, and shop. Many shops charge between $80–$150 per hour; dealerships and metro areas may be higher, independents may be lower.

Frequently Asked Questions about P1223 Code
1. What are the common symptoms of OBDII code P1223 (Throttle Position Sensor 2 Circuit Low Input)?
The common symptoms include poor acceleration, rough idling, stalling, and the vehicle going into "limp mode."
2. What are the possible causes of OBDII code P1223?
Possible causes of this code include a faulty throttle position sensor, damaged wiring or connectors in the throttle position sensor circuit, or a problem with the engine control module.
3. How can I diagnose the cause of OBDII code P1223?
Diagnosing the code typically involves using a scan tool to read the code and data from the throttle position sensor. Checking the sensor's wiring and connectors for damage is also important.
4. Can a dirty throttle body cause OBDII code P1223?
Yes, a dirty throttle body can cause erratic readings from the throttle position sensor, leading to the code being triggered.
5. Is it safe to drive with OBDII code P1223 active?
It is not recommended to drive with this code active, as it can lead to poor engine performance and potential safety hazards.
6. How can I repair OBDII code P1223?
Repairing this code may involve replacing the throttle position sensor, repairing damaged wiring or connectors, or resetting the engine control module.
7. Can I clear OBDII code P1223 without fixing the underlying issue?
Clearing the code without addressing the root cause may temporarily turn off the check engine light, but the issue is likely to recur if not properly repaired.
8. Will OBDII code P1223 cause permanent damage to the engine?
While the code itself may not cause immediate damage, ignoring the underlying issue can lead to poor engine performance and potential long-term damage if left unresolved.
9. How much does it typically cost to fix OBDII code P1223?
The cost of fixing this code can vary depending on the root cause, but it may involve labor costs for diagnosis and repair, as well as the price of any parts that need replacement.
10. Can I prevent OBDII code P1223 from occurring?
Regular maintenance, such as cleaning the throttle body and inspecting the throttle position sensor, can help prevent this code from occurring.
