Fault codes p0106, p0121 daewoo lanos 2002 1.6i sport

I suggest you get one of those manuals people get nowadays to do it yourself.. My nephew use it to repair my car and it's totally repaired now. Here's the website he bought it from.

That is a MAP sensor failure. On the intake to the engine there is a sensor that measure the atmospheric pressure. Replace the sensor.

first cde is engine is running to rich second code you have a large leak at the evap system

P4040 code that is a non specific code that could be either EGR control circuit malfunction or security shut down mode meaning that the security system is shutting off the spark and/or fuel.

The fault code 53 is an ECM IMMOBILIZED ERROR.
The immobilizer anti-theft system thinks the key is invalid. If it detects an error, it will;
Disable the fuel injector circuit--- Disable the fuel pump circuit---Disable the ignition coil.

Code 53 will set when:
1- The Eectronic Control Module (ECM) does not receive the signal from the Immobilizer Control Unit (ICU) within 0.9 seconds when vehicle is stationary, or 1.8 seconds when vehicle is moving.
2- The ICU sends the ECM an incorrect release message more than 5 times.
3- The above conditions continue until the ignition is switched off.

I hope this helps.

OBD II Fault Code

• OBD II P0106

Fault Code Definition
The Manifold Absolute Pressure Sensor/Barometric Pressure Sensor measures the rise and fall of the air pressure inside the Intake Manifold. This provides critical data needed for the Power Train Control Module (PCM) to control the Air Fuel Ratio, the Ignition Spark Timing, and many components of the Emissions Control Systems. The Manifold Absolute Pressure/Barometric Pressure Sensor P0106 code is set when there is a problematic or erratic performance in the voltage signal to the PCM.
Symptoms

• Check Engine Light will illuminate
  
• In many cases, no abnormal symptoms may be noticed
• In some cases, the engine may be hard starting and/or get poor fuel economy
• In some cases, noticeably poor engine performance may occur

Common Problems That Trigger the P0106 Code

• Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is defective
  
• Intake Manifold vacuum leaks
• Faulty or corroded Manifold Absolute Pressure Sensor/Barometric Pressure wiring or connections

Common Misdiagnoses

• Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is an Intake Manifold vacuum leak
  
• Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real cause is a stuck-open EGR Valve
• Manifold Absolute Pressure Sensor/Barometric Pressure Sensor is replaced when the real problem is a defective Idle Air Control Motor, which causes a very low engine idle

it may need spark plugs and wires

P0174

P0335

P0340

P0385

P0442

P0506

P0507

P0601.

all of the above codes seem to have a common cause, they all list a bad ecm (computer) as being a cause, and the last code P0601 points specifically to a bad computer. sorry for the bad news, hope this helps.

DTC 63 Will Set When
No voltage is supplied by the ECM through the EST “B” line while reference pulses are received by the ECM from the crankshaft position sensor
check white wire terminal B on ignition coil to ECM terminal C14 for open circuit or short to ground while disconnected if thats ok check for voltage signal at B while cranking no signal ECU faulty. voltage signal also on A terminal while cranking and check earth terminal C to body no higher than 5 Ohms
power is terminal D 12V
if getting power, earths good, and both signal voltages are going into coil pack, coil pack is faulty.

This may be happening because the sensor is open circuit (sensor fault) check the sensor
