Question about 2004 Nissan Sentra

Throttle position sensor

Hi my 04 sentra 1.8 threw a code for the TP sensor. The rpms surge and die. I replaced the throttle unit. It still does it. What else could it be? Is there a wire or connector that could do this?

If the code keeps comming back then you would first find the wire that goes from the tps to the computer. check for the five volt reference voltage, at the computer and at the tps and then check to see if the return voltage is also at the computer. ( this wire sometimes breaks)

When I push my gas pedal down about one inch the reduced power light comes on it don't stall just reduced power you shut the truck off restart it the light is off ,


The reduced power light is pertaining to the TAC - electronic throttle control . Is the check engine light lit ? If not still may have a DTC -diagnostic trouble code stored . You probably have a bad TPS - throttle position sensor .
Throttle Body Assembly
The throttle body for the throttle actuator control (TAC) system is similar to a conventional throttle body with several exceptions. One exception being the use of a motor to control the throttle position instead of a mechanical cable. Another exception is the throttle position (TP) sensor. The TP sensor is mounted in the throttle body assembly. The TP sensor is 2 individual TP sensors within the throttle body assembly. Two separate signal, low reference, and 5-volt reference circuits are used to connect the TP sensors and the powertrain control module (PCM). TP sensor 2 signal voltage increases as the throttle opens. TP sensor 1 signal voltage decreases as the throttle opens.

I have codes: po455, po123. po406 po606.p2104, po2106, p2110, & p2135 help please!


(so i cleared the code..all was fine.) No it wasn't ,you don't just clear code's without doing the diagnostic's for that code . It's just a matter of time ,when the PCM/ECM - engine computer runs that test again, that light will come back on. P0455 is a large leak in the evaporative emission system .Sorry dude but you don't stand a snow ball's chance in guam of fixing this .
Do you know what electronic throttle control is ?
P2135 - ETC Throttle Position (TP) Sensor A/B Voltage Correlation Description: The powertrain control module (PCM) flagged a fault indicating that TP1 and TP2 disagree, or that TP1 should not be in the present position given the position of TP2 unless a concern is present. Possible Causes:
  • TP sensor shorted internally to VREF.
  • TP sensor harness is shorted to power.
  • TP sensor signal wires are shorted together.
  • Damaged TP sensor.
Diagnostic Aids: Compare the TP1 and TP2 PID values for a full sweep and correlation. Refer to the chart in pinpoint test DV. GO to Pinpoint Test DV .
Compare TP1 and TP2 PID values to the typical reference values in Section 6 . Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV4
P2110 - Throttle Actuator Control (TAC) System - Forced Limited RPM Description: The TAC system is in the failure mode effects management (FMEM) mode of forced limited RPM. Possible Causes:
  • Cross-wired TAC motor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC indicates only that the FMEM condition exists, and can be set in combination with DTCs P2100, P2101, or P2107, meaning the electronic throttle body (ETB) faults should be diagnosed first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1
Do yourself a favor an take it to a qualified repair shop.

Code p2138


P2138 is Throttle Pedal Position Sensor/ Switch D / E Voltage Correlation. Replace the Throttle Pedal Position Sensor/Switch.Remember to have the set code Cleared from the cars computer, this will turn off the check engine light and reset it. Good Luck and have a good XMASS.

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!!

I have a 2004 jeep wrangler and i am reading the codes p0122 p0123 and p0432 can anyone let me know what these dtc's mean and if possible how to fix what it broken


P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
P0123 - Throttle Position (TP) Sensor Circuit High Voltage
without checking it 1st I would guess the TPS is most likely defective.
P0432 - Catalyst System Low Efficiency Bank 2, you may have to replace the Catalytic convertor, it may be worn out,
A WORD OF CAUTION: Don't use aftermarket cats, they tend to reset the same code due to compatibility issues, also replace the cat monitor sensor (looks like an O2 sensor) located just to the rear of the bank 2 cat converter.
