How to diagnose p0120 TP sensor 1 malfunction?

This test tutorial will help you diagnose a P0120: Throttle Position (TP) Sensor 1 Malfunction with the Throttle Actuator Control (TAC) Throttle Body in a step-by-step manner using only a multimeter.

What are the symptoms of the p0120 OBD-II trouble code?

The ECM detected that the output from TPS sensor circuit A went outside of the specified voltage range in relation to TPS sensor circuit B. The TPS sensor circuit A output falls below .2 volts or goes above 4.5 volts. What are the symptoms of the P0120 code?

What is a trouble code for TPS a?

P0120 is a diagnostic trouble code (DTC) for “TPS “A” Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $70.00.

What is the OBD code for a TPS sensor?

P0120 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS sensor circuit A output voltage going below or above the sensor’s expected range, or is chattering when compared to TPS sensor circuit B.

This test tutorial will help you diagnose a P0120: Throttle Position (TP) Sensor 1 Malfunction with the Throttle Actuator Control (TAC) Throttle Body in a step-by-step manner using only a multimeter.

What causes a p0120 code on a throttle return?

Potential causes of the P0120 code include: Sticking throttle return spring MAP or TPS connector corrosion Misrouted harness causing chafing Bad TPS Bad PCM

What are the p0120 and p2135 codes?

I have 2 codes P0120 and P2135, I first replace the pigtail and TPS sensor same problem and codes (Reduced engine power). so i bit the bullet and replaced the throttle body along with another new TPS (it came attached ) still same problem…any help?… codes P0340 and P0120 please help!

What is the p0120 TPS signal voltage at WOT?

When the throttle is closed the signal is near .45 volts. At WOT (Wide Open Throttle) the TPS signal voltage will approach a full 5 volts. When the PCM sees a voltage that is outside of normal operating range, P0120 will set. NOTE: The PCM knows that any large change in throttle position means a cooresponding change in manifold pressure (MAP).

What does the TP signal mean on a car?

Lack of power when accelerating the engine. The Throttle Position (TP) Signal is less than 0.37 Volts or more than 4.51 Volts (for more than 1 second). You’ll see the message center display: ‘Reduced Engine Power’ (and of course the engine will operate in Reduced Engine Power mode).

How much does it cost to fix a p1120 code?

The cost of diagnosing the P1120 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour. The Throttle Position Sensor ( TPS) responds to the accelerator pedal movement.

How can you tell if your car has a p1120 code?

Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. How much do you know about cars? The cost of diagnosing the P1120 code is 1.0 hour of labor.
