SOURCE: check engine light on 2003 toyota tacoma, O2 sensor?

An O2 sensor code is a tricky one. It could mean SEVERAL different things, and I know how bad it sucks to hear this, but your best bet is to take it in and have a diagnostic ran on it at either a dealer or a good mechanic shop with a computer they can hook up to it. I had an "O2" code come up a while back on another car I used to have, and literally spent weeks and hundreds of dollars trying to fix it, and never did. Finally out of desperation took it in, paid the $90, and they found the problem and fixed it in like 30 minutes. Something I would have never even thought of was causing it (can't remember off the top of my head). After that I stopped wating time and money on check engine lights. One comes on in my car, I take it to have it ran for free at and auto parts store just to make sure it's not a loose gas cap or something, just to get an idea of what I'm looking at, then go and make an appointment to have to hooked up to a diagnostic computer to track down the problem. Good luck, and hope this helps save you some time and money.

I recommend you test the tps according to procedure below. Especially step 8. Suspect you will see drop outs in the voltage, which indicate sensor is worn out.

The Throttle Position Sensor (TPS) is mounted to the side of the throttle body and connects to the throttle blade shaft. The TPS is a variable resistor that provides the PCM with an input signal (voltage). The signal represents throttle blade position. As the position of the throttle blade changes, the resistance of the TPS changes.
The PCM supplies about 5 volts of DC current to the TPS. The TPS output voltage (input signal to the PCM) represents throttle blade position. The TPS output voltage to the PCM varies from about 0.5 volt at idle to a maximum of 4.0 volts at wide open throttle. The PCM uses the TPS input, and other sensor input, to determine current engine operating conditions. The PCM also adjusts fuel injector pulse width and ignition timing based on these inputs.

In order to perform a complete test of the TPS and related circuits, you must use a DRB or equivalent scan tool, and follow the manufacturers directions. To check the Throttle Position Sensor (TPS) only, proceed with the following tests.
  1. Visually check the connector, making sure it is attached properly and that all of the terminals are straight, tight and free of corrosion.
  2. The TPS can be tested using a digital ohmmeter. The center terminal of the sensor supplies the output voltage. The outer terminal with the violet/white wire is the 5-volt supply terminal and the black/light blue wire is the sensor ground terminal.
  3. Connect the DVOM between the center terminal and sensor ground.
  4. With the ignition key to the ON position and the engine OFF, check the output voltage at the center terminal wire of the connector.
  5. Check the output voltage at idle and at Wide Open Throttle (WOT):
  6. For 1996 vehicles at idle, the TPS output voltage should be greater than 0.35 volt (0.4 volt for the 2.4L engine). At WOT, the output voltage should be less than 4.5 volts (3.8 volts for the 2.4L engine).
  7. For 1997 and later vehicles at idle, the TPS output voltage should be about 0.38-1.20 volts. At WOT, the output voltage should be about 3.1-4.4 volts.
  8. The output voltage should gradually increase as the throttle plate moves slowly from idle to WOT.
  9. If voltage measures outside these values, replace the TPS.
  10. Before replacing the TPS, check for spread terminals and also inspect the PCM connections.

I need to know the code po120

Throttle Position Sensor/Switch (TPS) A Circuit Malfunction
The TPS (Throttle Position Sensor) is a potentiometer that is mounted to the throttle body. It detects the throttle blade angle. As the throttle blade moves, the TPS sends a signal to the PCM (Powertrain Control Module). Usually a three wire sensor: A 5 volt reference from the PCM to the TPS, a ground from the PCM to the TPS, and a signal return from the TPS to the PCM. The TPS sends the throttle position information back to the PCM on this signal wire. 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). On some models the PCM will monitor MAP and TPS operation for comparison. Meaning that if the PCM sees a large percentage change in throttle position, it expects to see a cooresponding change in manifold pressure and vice versa. If it doesn't see this comparitive change, P0120 may set.

My '05 Tacoma 3.5L has developed a quick skip or hesitation when I excelorate. I had the spark plugs replaced but the problem continues.

Could be a problem with the throttle position sensor. If the carbon track on which the throttle plate slider contact runs has dirt on it or is worn then this would interrupt signal to the ECU. The TPS has three pins in the socket. Two (usually the outer two) supply the 5 volts reference and 0 volts ground to the carbon strip. the middle pin measures the voltage 'tapped' by the throttle position sliding contact. Disconnect the TPS lead and with a voltmeter simply measure the resistance between one of the outer pins and the middle pin as the throttle plate is opened and closed. The response should be smooth chnage in resistance with no 'drop-outs'. If a drop is consistently detected at a particular throttle plate position then the TPS needs to opened and cleaned if dirty or replaced if faulty.

2002 tacoma p 1300 truck runs for 6 seconds then dies

Hi and welcome to FixYa!

Two things to look at to resolve the problem. You may have a faulty MAF (mass air flow) sensor and TPS (throttle position sensor). If one of these sensors are faulty the car tends to die or an erratic idle can be expected. You will need to have it replaced to resolve the problem.

Hope this helps and thank you for using FixYa! Have a good one!

Code p0122 and p0123 after changing computer


The problem is regarding TPS (throttle position sensor located in throttle body). Both codes are TPS voltage out of range (low and high) If you get both codes at once, then :

TPS may be defective,
wiring to TPS may be shorted to ground.
There may be a problem in the +5V circuit powering the TPS.
There may be a problem with ECU connector.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.

I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!
