[SOLVED] P1514 Code: Fix Throttle Actuator Control System Mass Air Flow Performance!

The automobile fault code P1514 indicates a problem with the Throttle Actuator Control (TAC). The most common symptom is the Engine Light being ON or the Service Engine Soon Warning Light.

The cause of this fault code can be a faulty TAC, an open or shorted TAC harness, a poor electrical connection in the TAC circuit, or a faulty Mass Air Flow (MAF) Sensor. To fix this issue, you should visually inspect the wiring harness and connectors, checking for any damage or corrosion.

Additionally, look for any broken, bent, pushed out, or corroded pins in the connectors.

The repair time for this issue is estimated to be around 1.0 hour.

Repair Importance Level10.0 (Out of 10)
Estimated Repair TimeApproximately 1.0 hour
Repair Difficulty Level6.67 (Out of 10)

When the engine light is on or the service engine soon warning light is illuminated, it could be a sign of the p1514 fault code.

  • The symptoms of the automobile fault code p1514 include the Engine Light being ON or the Service Engine Soon Warning Light being illuminated.

The automobile fault code p1514 can be caused by a faulty Throttle Actuator Control (TAC), an open or shorted TAC harness, a poor electrical connection in the TAC circuit, or a faulty Mass Air Flow (MAF) Sensor.

The P1514 fault code refers to a problem with the Throttle Actuator Control (TAC) system. This system uses electronic components to calculate and control the position of the throttle blade, eliminating the need for a mechanical cable. It also handles cruise control functions.

The TAC system includes the accelerator pedal position (APP) sensors, the throttle body, and the Powertrain Control Module (PCM). These components work together to ensure accurate calculations and control of the throttle position (TP).

In the case of the P1514 code, it specifically relates to the Throttle Body Assembly. This assembly is similar to a conventional throttle body but uses a motor instead of a mechanical cable to control the throttle position. It also includes two individual TP sensors within the assembly.

These sensors have separate signal, low reference, and 5-volt reference circuits that connect to the PCM.

The signal voltage of TP sensor 2 increases as the throttle opens, while TP sensor 1 signal voltage decreases. Overall, the P1514 fault code indicates an issue with the Throttle Actuator Control System Mass Air Flow Performance.

What are the possible causes of the automobile fault code p1514?

If you’re seeing the engine light on or the service engine soon warning light, the fault code P1514 might be the culprit. This code is often caused by a faulty throttle actuator control (TAC), an open or shorted TAC harness, a poor electrical connection in the TAC circuit, or a faulty mass air flow (MAF) sensor. To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components and check for broken, bent, pushed out, or corroded connector pins. Don’t forget to check the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the p1514 fault code?

If you’re dealing with the p1514 fault code and notice that your engine light is on, it’s time to take action. The most common causes of this code are a faulty Throttle Actuator Control (TAC), an open or shorted TAC harness, a poor electrical connection in the TAC circuit, or a faulty Mass Air Flow (MAF) Sensor. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken or bent pins, corrosion, or components that are out of place. This simple step can help you identify and resolve the problem.

What should I look for when checking for damaged components and connector’s pins to resolve the p1514 fault code?

If you’re dealing with a p1514 fault code, there are a few things you should check for. Start by looking out for the symptom of the engine light being on. The cause of this issue could be a faulty Throttle Actuator Control (TAC), an open or shorted TAC harness, a poor electrical connection in the TAC circuit, or a faulty Mass Air Flow (MAF) Sensor. To fix the problem, visually inspect the related wiring harness and connectors. Pay close attention to damaged components and check for any broken, bent, pushed out, or corroded connector’s pins.
