What does code po120 mean?
What the P0120 code means. 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.
What happens when you put a p0120 code on an ECM?
The P0120 code will put the engine ECM to go into a failsafe mode, which will cause various drive complaints until repairs are done. For example, lack of acceleration, high idle, bucking or jerking, limited speeds, and possible stalling depending on the manufacturer failsafe mode strategy. What repairs can fix the P0120 code?
What’s the problem with the TPS code p0120?
The P0120 code may be accompanied by other TPS codes, so following the manufacturer pinpoint tests for each code received may be needed to fix the complaint. Most failures for code P0120 involve a defective TPS sensor not tracking the throttle angle correctly.
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 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 is the diagnostic code for TPS a circuit malfunction?
Cost of diagnosing the P0120 code. 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.
How do you test a Toyota throttle position sensor?
Touch the negative probe on the multimeter to the negative wire tab on the TPS and the positive probe to the positive tab. The multimeter will display around 5 volts if the TPS is working correctly. Check signal voltage. Touch the positive probe to the signal wire tab and touch the ground probe to the frame of the car.
How do I fix code P1516?
Make sure you check the ground wire from the TAC harness to the back of the engine block passenger side. In many cases, this could be the culprit of the code. Also in some cases, the throttle body plate could be sticking because of dirt. You can try cleaning the throttle body before replacing any parts.
How much does it cost to diagnose p0120 Toyota code?
The cost of diagnosing the P0120 TOYOTA 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. When is the P0120 TOYOTA code detected?
When does a Toyota engine have a trouble code?
This trouble code is usually triggered when the O2 sensor in position bank 1, sensor 1 is bad or has faulty wiring. Replacing the sensor will almost always get rid of the code.
What does the P0420 code on a Toyota mean?
P0420 Code – Toyota. All P042X codes (where “X” can be any number) refer to the catalytic converter and exhaust system. P0420 refers to the catalytic converter or – more specifically – the oxygen (O2) sensors before and after it on the bank 1 side of the exhaust system. On most vehicles, there is an O2 sensor both in front (upstream)…
What does the code p0125 mean on a Toyota engine?
If no information is coming from the sensor after the engine is warmed up, this will trigger the code P0125. Possible causes include low coolant, stuck or bad thermostat, or faulty sensor.
