please help ! NISSAN MICRA K13 1.2 acelarator pedal not working, throttle DTC"s

**mexanico1971** · 14th May, 2015, 01:13 PM

Hi People !
got this MICRA 2014 width pedal or throttle problem car got 600km !
Got nissan consult 4 and folling dtc"s

P2119 Throttle Actuator Control Throttle Body Range/Performance
P2135 Throttle Position Sensor Circuit Range/Performance
ABS C1130 engine signal
any experience on this problem ?
does it need to performe Throttle Body adjust ?
how to do it ?

updating post , car have a little accident and break right headlight

if I put the motor running and try to engage 1? gear , the engine shut down !

Than"k in advance

BR

No one ?? have any ideas :-(

Check the wires at the connector to the throttle body, seen a lot of different fly by wire systems have this problem it's a fairly common occurrence. Tug gently on each wire of the connector, a broken one will pull out easily.

Micra has a known problem with throttle body. Get another!

Hi !
new update !
today I check wires from F29 THP plug to the ECU ! ALL Ok :-)
I dissemble throttle body and test motor actuator !
But I need to test potentiometer throttle ?! it look"s that is open circuit ! or is only possible measure signal ?
I start think ecu flash is the problem , because if I step accelerator wend I start the engine , car rev until +/- 3000rpm !
and if I start engine and don"t step it idle get very unstable , and pedal not work at all !

Before you start testing on stuff like this it's important to have a proper wiring diagram and understanding of circuit design and operation.

Nissan throttle body wiring is all basically the same for the fly by wire and here are the 6 connections.

Power
Ground
Sensor1
Sensor2
Motor
Motor

Below is wiring for a different Nissan, the colors and pinouts may be different, but it's the same operation. 5V and Gnd are connected through the potentiometers so the ECU can verify the integrity of the circuits, if one fails or there is an open wire, it can detect the fault.

The wipers move on the sensors and return the voltage to the ECU on the sen1 and sen2 circuits. Most TPS are about 1V at closed throttle, and 4.5V at WOT. The ECU compares both sensor values and if there is a discrepancy between the two, it will set a fault code and can go into limp mode. When testing the sensor signals, you should have the throttle body plugged in and backprobe the connector with a paperclip, ONLY backprobe one at a time to prevent short circuit and damage.

These are just the basics, but maybe with some understanding of circuit design and operation you might get somewhere instead of random meter readings.

Hope this helps

Hi !
Does any one Knows what value in Ohms the potenciometer of have ?

wend I turn the potenciometer like he was on the body I do not get plausivel value !

thank"s in advance

**mexanico1971** · 24th June, 2015, 11:45 AM

People thank"s for the ideias !
But I do not have any voltage on the motor throttle body !
this is pedal not press

this is width the pedal fully press

do I have, to have some voltage on this terminal ?! Rigth ?

throttle body relay seems to work !
what send voltage signal to the throttle body motor flap ?

The pedal I would think. BUT, you cannot test if car is in LHM! Make sure you are looking for the fault, not the effect. If you have a fault elsewhere, power to the pedal is limited.

What you mean width " car is in LHM "
thank"s

LHM =limp home mode.

**lashkar97** · 25th June, 2015, 07:39 PM

my dear in all nissan this is common fault.so problem is not in APP sensor and not in TP Sensor you are wrong side diagnose the car . in nissan these both sensor work at 5volt so when 5volt gone short its give you like this code app or TP or CKP or CMP so please frist check throttle motor controlle relay is on or off postion check that in data stream if its off tri ignition on off and check its become on and then gone off or its not gone on even ignition on off . 2nd thing dissable all 5volt senor one by one . if its all is ok .then problem in ECU . SO repair Ecu

does any one knows were is the throttle body relay ??

thank"s in advance

Please check the following:
- ECTS Fuse.
- Throttle body M-, and M+ terminal resistance and voltage in the wires harness.
- Do the the throttle body learning.

Accelerator Pedal Released Position Learning

DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time harness connector of accelerator pedal position sensor or ECM is disconnected.

OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF and wait at least 10 seconds.

BASIC SERVICE PROCEDURE
2007 Armada

Throttle Valve Closed Position Learning
DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of electric throttle control actuator or ECM is disconnected.

OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

IDLE AIR VOLUME LEARN (Manually)
1. Perform Accelerator Pedal Released Position Learning.
2. Perform Throttle Valve Closed Position Learning.
3. Start engine and warm it up to normal operating temperature.
4. Check that all items listed under the topic PREPARATION (previously mentioned) are in
good order.
5. Turn ignition switch OFF and wait at least 10 seconds.
6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
7. Repeat the following procedure quickly five times within 5 seconds.
a. Fully depress the accelerator pedal.
b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds
until the MIL stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the MIL turned ON.
10. Start engine and let it idle.
