Cine stie sa repare calculator abs? in tm

salut,caut pe cineva care sa ma ajute sa scap si eu de o problema mai veche
se tot aprinde becul abs in bord de ceva vreme si la test mi s-a spus ca e cod 0121
si trebuie schimbat tot ansamblul frana care e destul de scump.
are cineva o alta solutie?sau vreun remediu?
sunt din tm si astept sa colaborez cu cineva pe tema asta

Esti sigur ca ala e codul?
Pentru ca uite ce am gasit eu despre mesajul ala de eroare:
P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Problem
OBD-II Trouble Code Technical Description

Throttle Position Sensor/Switch A Circuit Range/Performance Problem
What does that mean?

The Throttle position sensor is a potentiometer that measures the amount of throttle opening. As the throttle is opened, the reading (measured in volts) goes up. The powertrain control module (PCM) supplies a 5 Volt reference signal to the throttle position sensor (TPS) and usually a ground also. A general measurement is: at idle = .5 Volts; full throttle = 4.5 Volts. If the PCM detects that the throttle angle is greater or less than it should be for a specific RPM, it will set this code.
Potential Symptoms

Symptoms of a P0121 trouble code could include:

Malfunction Indicator Lamp (MIL) illumination (Check Engine Light or Service Engine Soon light)
Intermittent stumble on acceleration or deceleration
Blows black smoke on acceleration
No start

Causes

A code P0121 may mean that one or more of the following has happened:

TPS has intermittent open or short internally
Harness is rubbing and causing an open or short in the wiring
Bad connection at the TPS
Bad PCM (less likely)
Water or corrosion in connector or sensor

Possible Solutions

1. If you have access to a scan tool, see what the idle and WOT (wide open throttle) readings are for the TPS. Check if they're close to the specifications mentioned above. If not, then replace the TPS and re-check.

2. Check for an intermittent open or short in the TPS signal. To do that, you can't use a scan tool. You'll need an oscilliscope. The reason is because scan tools take samplings of many different readings over just one or two data lines and can miss an intermittent drop out. Hook up your oscilliscope and watch the signal. It should sweep up and down smoothly with no drop outs or spikes.

3. If no problems were noticed, perform a wiggle test. Do this by wiggling the connector and harness while watching the pattern. Does it drop out? If so, replace TPS and re-check.

4. If you have no TPS signal, check for 5 Volt reference at the connector. If it's present, check the ground circuit for open or shorts.

5. Make sure the signal circuit isn't 12V. It should never have battery voltage. If it does, trace circuit for short to voltage and repair.

6. Look for any water in the connector and replace TPS as necessary.

Codul e C0121, nu P0121.

mai intai de toate multumesc celor ce mi-au raspuns
acum vreau sa explic putin,nu sunt sigur acum care e exact codul din cate mi-aduc aminte asa era sau ceva asemanator oricum
e legat de abs sau valve multifunction
ce mi-ai spus adineaori nu este pt ca nu am acelel simptome la masina
masina este un vectra b 2 din 2001 y20dth
daca se repara sunt dispus sa o fac dar sa fie un specialist nu experimentar
spun asta pt ca am mai patit-o
va multumesc

pentru tine apeleaza la maiandrei

Da tu .
