My Civic 08 Japan model has been acting up.

First, you can't start it once and move because the throttle won't respond (electric throttle), expect turning it on severally before the throttle responds.

It is worse these days as the throttle responds will just seize while in motion, rough idle (fluctuates btw 300rpm to 700rpm) and brake and quench.

I scanned and three codes popped up:
1.P2138
2. P2176 (throttle idle position not learned)
3. p0013


Pls, is changing the throttlebody the best solution or fixing?

Requests for 3 parts but don't pay yet.

Engine ecu

Throttle body

Throttle pedal .


The codes point to a faulty pedal and an unlearned idle .

Replace the throttle pedal or pedal app.

Clear codes and test vehicle.

If this does not work, swap the other two parts sequentially and test, one of them should solve the problem.

Return the parts you do not need .

Good luck.

lordm:

Check Plugs, Fuel filter/pump and air filter. Go to your mechanic

Thanks. The Throttle body has been replaced and the car starts normally but sometimes, the idle speed is not stable (fluctuates between 800rpm to 1300rpm. The P2138code etc has cleared.

Although, the electrician said that "computer" has to be used to relearn the idle speed.

And a new code is now showing P1659. Any solution.

P1659 HONDA Meaning
The Powertrain Control Module (PCM) controls the throttle valve opening. The system includes the throttle actuator, the throttle valve, Throttle Position (TP) sensors A and B, the Accelerator Pedal Position (APP) sensor, the Electronic Throttle Control System (ETCS) control relay, and the PCM. The APP sensor is operated via the throttle cable to determine the accelerator opening value when the driver presses the accelerator pedal. The accelerator pedal opening value is converted to a signal in the APP sensor and transmitted to the PCM to compute the target position. The PCM determines the throttle valve target position according to the signal received and operates the throttle actuator to move the throttle valve to the target position. The actual throttle valve position is determined by TP sensor A (installed in the throttle body). When the voltage is applied from the ETCS control relay to the IG1ETCS terminal for a set time after the ETCS control relay is turned off, the PCM detects a malfunction in the ETCS control relay power switch and a DTC is stored.

Possible throttle body failure or Engine ECU

sultaan:
you have a vacuum leak, one of the black hoses is disconnected.
Start with the brake booster hose then the hose for the PCV valve(just google the image for this parts on your car and compare the connection).

Your problem is a damaged ,cracked, or disconnected don't go spending money on a simple problem, there might be a black hose on the throttled body disconnected

I scanned and three codes popped up:
1.P2185: Engine coolant temperature sensor 2 circuit high
2. P2176 -throttle actuator control system- idle position not learned (the only code that has been seen since months ago).
3. P0013 - Engine coolant temperature sensor 2 circuit high

It showed the P2135 code but I cleared the code and I stopped seeing it. Could come back. I tried to floor the accelerator 3 times while engine is 'on' but not running. (A tip I saw on Honda group online about how to recalibrate pedal position).

Go change your knock sensor.

Oga don't start changing parts anyhow o. I had this same issue two weeks ago. Car wasn't firing. Brand new Honda Accord engine wey I just buy. I knew it couldn't be engine. I noticed it started when I entered in water with full speed. Car no longer accelerating. Wouldn't rev beyond 2000. My mechanic started touching and mentioning different sensors. He even suggested I buy a new injector head. I said never how can a direct sharp Belgium engine suddenly be having injector head issues.
Long story short d same mechanic directed me to another technician who scanned my car properly. That actuator error code popped up. The man connect laptop that was when I knew some ppl actually know how to fix cars. In less than two hours d guy fixed the electrical stuff and my car has been perfect since then.
