Actron CP9190 manual CLR TIM 0 65,535 min or 0 1092.25 hours

PID Definitions

CAT TEMPxy (- 40 – 6513.5ºC) or ( - 40

– 9999.9ºF)

Catalyst Temperature displays the cata- lyst substrate temperature for a Bank x catalyst (if used by control module strat- egy for OBD monitoring) or displays the Bank x Sensor y catalyst temperature sensor.

CLR DST (0 – 65,535 km) or (0 – 40,722 miles)

Distance Since Cleared Diagnostic Codes is the distance driven since diag- nostic trouble codes were erased.

CLR TIM (0 – 65,535 min) or (0 – 1092.25 hours)

Time Since Cleared Diagnostic Code is

time since diagnostic trouble codes were erased.

CMD EQ RATxy (0 – 1.99)

Commanded Equivalence Ratio is the

ratio of the air/fuel mixture.

•For systems that use conventional oxygen sensors, the commanded equivalence ratio displays in open loop. In closed loop, the value is 1.0.

•Fuel systems using wide-range/lin- ear oxygen sensors display com- manded equivalence ratio in both open and closed loop operation.

COOLANT (- 40 – 215ºC) or (- 40 – 419ºF)

Coolant displays engine coolant temper- ature (ECT) from a ECT sensor or cylinder head temperature sensor.

✓Many diesel engines do not use either sensor and may substitute Engine Oil Temper- ature instead.

EGR CMD (0 – 100%)

Commanded Exhaust Gas Recirculation

is the normalized percentage of exhaust gas being recirculated.

EGR ERR (-100 – 99.22%)

Exhaust Gas Recirculation Error shows

A the error from changing from one condi- tion to another.

ENG RUN (0 – 65,535 sec.)

Time since Engine Start is the time the

engine is running.

✓ENG RUN stops when engine stalls or engine is turned off for any reason.

ENGINE (0 – 16,383.75 RPM)

Engine is the speed engine is running in revolutions per minute (RPM).

EQ RATxy

O2 Sensor Equivalence Ratio is used for linear or wide-ratio oxygen sensors for Bank x Sensor y.

EVAP REQ (0 – 100%)

Commanded Evaporative Purge is the position evaporative purge control valve is open in percentage.

EVAP VP (- 8192 – 8191 PA) or (- 32.8878 – 32.8838 H20)

Evaporative E missions System Vapor Pressure is pressure in the fuel tank

FUEL LVL (0 – 100%)

Fuel Level Input is the percentage of fuel with 0% equaling tank is full and 100% when tank is empty.

FUEL PRES (0 – 765 kPa) or (0 - 110 psi) Fuel Rail Pressure is the fuel pressure at the engine when reading in reference to atmosphere pressure.

FUEL SYS (OPEN or CLSD)

Fuel System Status show loop status of fuel system banks.

OPEN: Module is operating in Open Loop control strate- gy. The vehicle has not yet satisfied conditions for Module to go to closed loop.

CLSD: PCM currently functioning in Closed loop control strat- egy, using O2 sensor(s) as feedback for fuel control

OPEN1: Open Loop control strategy is being used by the PCM due to driving conditions.

Driving conditions that may cause this to happen are power enrichment and de- celeration enrichment.

OPEN2: The PCM is operating in Open Loop control strategy due to detected system fault. Certain actuator or sensor faults will cause module to use an open loop strategy.

CLSD1: Closed Loop control is cur-
