Hey what's this trouble code meaning p1590 TCSS TECM ECU ECM

You need a good auto-electrician to diagnose and fix that lot!

What the P2422 code means. The P2422 diagnostic trouble code is an indication that the vent valve of the evaporative emissions control system (EVAP) is stuck closed. The EVAP system reduces harmful pollutants, generated by the engine combustion process, from being expelled into the environment.P2422 OBD-II Trouble Code: Evaporative Emissions Control ...

The P2127 code means that the throttle or pedal position sensor switch E has a low input. The pedal position sensor is a sensor found on the gas pedal. The sensor tells the ECU when the gas pedal is depressed and how far it is depressed.

The P2138 trouble code indicates that the Engine Control Module has detected a malfunction within the D and/or E circuits of the throttle position sensor.

Ecu 1 fault means the engine EMC has a internal fault and needs to be replaced. Most of the time with this code It's not the ecm itself it's usually a wiring problem going to ECM. Their should be two fuses for ECM either next to ECM in plastic covers or by starter or in battery box. So you need to check all your wiring going to and from engine ECM (it's on drivers side of engine) and all your engine, starter, and battery grounds. Most of the time its a bad ground wire so take your time and check all over for any place that wiring could get rubbed through and all your connections are clean and tight. You would also want to disconnect battery negative while your doing this or it will log a bunch of other codes. Make sure all connection are corrosion free clean them as needed.

If you got a trouble code for this problem, what was the code? If you think it is a coil issue, check primary voltage and ground for the coil, engine cranking. Go from there

if the check engine lite doesn't work it most likely needs cluster removed and bulb replaced its blown. if the computer is bad it wont run. I wanna say that ecu fuse will clear code from computer but its not main power to it. I would start with the bulb that way you can get code.

read the FSM book yet or alldata.com???????
2106
2L automatic?

says
Trouble Code: P2106 (2.0L L4 VIN - Auto)
Throttle Actuator Control (TAC) System Performance - Throttle Limitation Active
Number of Trips to Set Code: 1
Trouble Code Conditions:
Ignition ON. The ECM detects the system is in Limit Performance Mode.
Possible Causes:

• Throttle body

this means the ECU is in limphome mode.
and is cause because the ECU sees throttle sensors. that dont JIBE
There are effectively (insane yes) 4 TPS sensors
2 under foot.
2 in TB.
if any disagree at any time BAM, limphome mode sets.
"limited performance, old suz name was FAIL SAFE.
no matter its just the same.
use a REAL scan tool that sees ALL codes, i suspect you missed some, is this an AUTOZONED scan? with cheap, tool?

try an Innova 3160 tool. and see them all.

it is suspisious to me , only ONE DTC error !!!

This Diagnostic Trouble Code (DTC) is output when the Engine Control Module (ECM) detects errors in communication between the Transponder Key Electronic Control Unit (ECU) assembly and the ECM, or in the communication lines. This DTC is also output when an engine start is attempted while the ECU communication ID between the transponder key ECU assembly and the ECM is different.
Possible causes Faulty Key Faulty transponder key amplifier Faulty Transponder Key Electronic Control Unit (ECU) Transponder key amplifier wire harness Faulty Engine Control Module (ECM)

First off, let's simply define the OBD-II Trouble Codes:
Yes, 18032/P1624/005668 are the three codes that indicate "MIL Request Signal Active."
So, what does THAT mean (in plain English)??? This means that Fault Codes are stored in the TCM. SO WHAT'S THE SOLUTION?

Your vehicle engine systems are run by a computer, called the ECU or ECM. There are others of these too, possibly one to run the auto trans.

There are several inputs to the ECM from things like vacuum and engine speed. When the ECM senses something is abnormal, the check engine light comes on. This may be only a minor thing, or something more serious.

The ECM has a connector to read out a code which will tell what it thinks the trouble is. If in the USA you can buy one of these trouble code readers and use it yourself. Some cars like Camrys have a simpler method to read the code just by connecting 2 terminals in a junction box under the hood.

Once you find out what the trouble code means, you can take steps to fix it. Then the trouble code has to be reset to normal, which is simple.

It means your on board computer, or ECM, is faulty and will need to be replaced.

thats the ecu telling u that ur vechicle is due for a service
