No DTC definition code found p1114


Hi there:
DTC P1114 - Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage/IAT - B Circuit Low Input



The engine coolant temperature sensor is a thermistor (a resistor which changes value based on temperature) mounted in the engine coolant passage. Low coolant temperature produces a high resistance 100,000 ohms at -40 oC (-40 oF) while high temperature causes low resistance 70 ohms at 130 oC (266 oF).

OPERATION
The VCM supplies a 5 volt signal to the engine coolant temperature sensor through a resistor in the VCM and measures the voltage. The voltage will be high when the engine is cold. The voltage will be low when the engine is hot. By measuring the voltage, the VCM calculates the engine coolant temperature. Engine coolant temperature affects most systems the VCM controls.

The scan tool displays engine coolant temperature in degrees. After engine start-up, the temperature should rise steadily to about 9O oC (194 oF) then stabilize when thermostat opens. If the engine has not been run for several hours (overnight), the engine coolant temperature and intake air temperature displays should be close to each other. When the VCM detects a malfunction in the Engine Coolant Temperature (ECT) sensor circuit, the following Diagnostic Trouble Code (DTC) s will set.



Hope this helps.

P1411 = Secondary air injection system, bank 2 - insufficient flow detected.
Probable cause: Intake leak, hose(s) blocked / leaking, secondary air system valve / solenoid.

P1423 = Secondary air injection system, bank 1 - insufficient flow detected.

Have an engine code for a check engine light 1423 and 1411 for an Audi A6 Quatro 2001


P1411 - secondary air injection system flow too low Bank 2.
P1423 - secondary air injection system flow too low Bank 1.
Check vacuum hoses to combi valves ,
most common split air injection pump which is riveted with aluminum rivets,ck rivets if they coming out ,pump doesn't build enough pressure.
In this case take pump out and put bolts instead of rivets all around pump case.Repl. all rivets not only broken one.Bolts sold at HomeDepot , just find a needed size.
