SOURCE: Check engine light

Funny that they changed the temp guage sensor....known problem on pre-2001 Audi TT and VW engines. Maybe yours was an early build 2002, so they helped you avoid a future problem.
As for the air flow, another known problem is the MAF (mass airflow) sensor. Don't panic, as this is a do it yourself job. Very likely problem if you ever installed a K&N type aftermarket air filter. These oiled filters cause buildup on the sensor. Free fix is to take the sensor body off (its the big ring/pipe coming off the air filter box before the rubber air intake hose) and clean the senor with isopropyl alcohol. Sensor body comes off by loosening the hose clamp on one end, and two screws into the filter box on the other. Don't forget to release the wiring harness plug by gently releasing the tab with a flat head screwdriver.
If your not comfortable with the cleaning, just find the MAF part on-line...about $200 bucks for a new one from Bosch. Very easy to do it yourself and a common failure point on the Audi.
For those still having the coolant sensor problem, also easy to replace yourself....about $10 bucks with a new o-ring.
Like GURU said, a code reader tool will tell if you have these problems, after the engine light comes on.

P0441 what dose it mean and how can I fix it .toyota camery le 1998model


P0441 1998 Toyota Camry - Evaporative Emission Control System Incorrect Purge Flow

When is the code detected? Pressure in charcoal canister and fuel tank does not drop during purge control (2 trip detection logic).

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Possible a noticeable fuel odor caused by the release of fuel vapors

P0441 1998 Toyota Camry Description: The Engine Control Module (ECM) tests the Evaporative Emission (EVAP) system for the following conditions:
- Large and small leaks

- Excess vacuum

- Purge flow during non-commanded conditions

- Fuel Level and Fuel Pressure sensor faults

- EVAP Purge and Vent Valve faults

The ECM monitors the Fuel Tank Pressure sensor in order to determine the level of vacuum/pressure in the EVAP system. The ECM commands both the EVAP Purge Solenoid and the EVAP Vent Valve ON when the conditions are met in order to apply an engine vacuum to the EVAP system. The ECM commands the EVAP Purge Solenoid OFF once the system has reached a predetermined level of vacuum. This test verifies if a vacuum can be achieved in the EVAP system. Failure to develop a vacuum may be caused by a large leak or a restriction.

Possible causes - Missing Fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- Incorrect fuel tank vacuum relief valve

Solution for engine check up light for code p0441 for hyundai accent 2001


P0441 Evaporative Emission Control System Incorrect Purge FlowOBD-II Trouble Code Technical Description

Evaporative Emission Control System Incorrect Purge Flow
What does that mean?

This indicates that a part of the EVAP control system is no longer functioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

EVAP emission canister purge is controlled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.
Symptoms

Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.
Causes

A code P0441 could mean one or more of the following has happened:

  • Bad vacuum switch
  • Broken or damaged EVAP line or canister
  • Open in PCM purge command circuit
  • Open or short in Voltage feed circuit to Purge Solenoid
  • Faulty purge solenoid
  • Restriction in EVAP solenoid, line or canister
  • Corrosion or resistance in purge connector
  • Bad PCM
Possible Solutions

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

  • Common Chrysler fix - Replace Leak Detection Pump / LDP
  • Repair damaged EVAP lines or canister
  • Repair open or short in voltage feed circuit to Purge Solenoid
  • Repair open in PCM purge command circuit
  • Replace purge Solenoid
  • Replace vacuum switch
  • Repair restriction in Evap line or canister or solenoid
  • Repair resistance in purge connector
  • Replace PCM
