SOURCE: pedal position malfunction

You can change the tps alone. You do not have to change the entire throttle body. It shouldn't be riveted in place, it should have screws or bolts on one side or the other. If it's riveted in place, use a dremmel and grind the rivets off. You can replace rivets with screws on the new unit.

If you can get a good scanner plugged into it, you can read the TPS as you slowly depress the throttle to see if it has a dead spot. This is the best way to view the TPS as well as the communication to the computer. You will see it "count" up on the scanner screen.

SOURCE: 1995 nissan pickup throttle position sensor

ok on a 2.4l on the black/green and white wires use ohm meter and there is no specific spec for that engine just make sure the the resistance changes and there is no dead spots. for the 3.0l black and white wires specs are 1.0-9.0k ohms im guessing the specs are the same either engine. close to full open

Hi, Check fuel filter and replace. Check and replace sparkplugs. Check ignition components. coil, wires, distributor for cracks. and then check for codes. Good luck.

Tip

Throttle Actuator Control - drive by wire


1.5) TAC - Throttle Actuator Control
What is it? Some vehicles have indirect throttle control "drive by wire". Instead of the accelerator pedal position being conveyed directly to the throttle plate by cable linkage, it is detected by an electrical sensor and this is fed to the ECU. The ECU in turn sets the position of the throttle plate appropriate to the sensed position using an electric motor. The throttle plate position is, in turn, checked by the throttle position sensor and this signal is sent to the ECU to confirm that the requested throttle plate setting and its recorded position are in agreement.

Where is it located? The first part of the TAC is located on the inner wing/fender and consists of rotary device to which the accelerator cable is attached; the degree of rotation (pedal depression) is detected electrically and this is signalled to the ECU. The second part of the TAC is located on the throttle body and acts on the throttle plate shaft.

Symptoms of a faulty TAC
Associated OBD2 error codes DTCs: P0120, P0124, P1516; P2102, P2103;P2111 - P2118

  • Sudden power loss/limp home: If the ECU detects any fault with the throttle actuator control directly or with the position feedback via the TPS it engages an immediate engine shut-down to either idle speed or limp-home speed.

How to fix? The TAC is part of complex systemand the failure of the TPS has to be eliminated first as a possible source of error. A simple electrical connection failure can also give rise to the shutdown so all associated connections should be checked to ensure that they are clean and bright to allow electrical continuity.

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.

P0020 Camshaft Position Actuator Circuit (Bank 2)
This sounds to me like a problem with the electrical connections in the multiplug sockets ,the previous problems were 3 yrs ago but check out that you do not have a siemans coumpter these are prone to weird and wonderfull faults .Normally once you start getting cam sensors and crank sensors then misfire 1/4 and so on this is a prelude to a faulty computer .

96 nissan quest code p0120 p1705 the O/D flushes after startup. TPS was replaced but code still exists. Rough idle, loss of power and fuel economy.


this is an obd2 trouble code table, it can help you understand the meaning of code.
and for p0120
the Causes:
Sticking throttle return spring
MAP or TPS connector corrosion
Misrouted harness causing chafing
Bad TPS
Bad PCM
Possible Solutions:
If you have access to a scan tool, with KOEO (Key on engine off) observe the TPS voltage. With throttle closed, voltage should be about .45 volts. It should gradually sweep upwards to approximately 4.5 to 5 volts as you depress the throttle. Sometimes only a scope can capture an intermittent glitch in the TPS signal voltage. If you notice a glitch in the TPS sweep voltage, replace the TPS.
NOTE: Some TPS sensors require fine adjustment. If you aren't comfortable with using a DVOM (Digital Volt Ohm meter) to adjust the new TPS, then it's best to take the vehicle to a shop. If the voltage is not .45 volts (+or- .3 volts or so) with the throttle closed or if the reading is "stuck" then unplug the TPS connector. With KOEO check for 5 volts reference voltage present at the connector and a good ground. You can check the signal circuit for continuity by jumping a fused wire between the ground circuit of the TPS connector and the signal circuit. If the TPS reading on the scan tool now reads zero, then replace the TPS. However if that doesn't change the reading to zero, then check for an open or a short on the signal wire and if none is found, suspect a bad PCM. If manipulating the TPS wiring harness causes any change in idle, then suspect bad TPS.

The reduce engine light comes on at 50 mph what could the problem be


DTC P0120 P0220 P1516 P2135 these should be the problem codes.
2003-2006 Chevrolet Avalanche, Corvette, Express, Monte Carlo, Silverado, SSR, Suburban, Tahoe, Trailblazer. for reduced engine power. p0120 is throttle position sensor, ( tps ). p0220 is relates to tps, p1516 tps is out of range. p2135 is a throttle body code, the throttle body needs replaced. but before you do it replace tps first to see if it takes care of the other codes. have a good day !!
