26 The network of sensors has the job of converting information the computer needs into electrical signals the computer can understand. Signals running from sensors to the PCM are referred to as inputs. Sensors monitor the key parameters shown in the table. NOTE: Not all engines use every sensor listed. Relays and Actuators Relays and Actuato[...]

27 Open and Closed Loop Modes: Open or closed loop operation refers to the way the computer is deciding how much fuel to add to the air entering the engine. During cold start and other low temperature situations, the computer operates in open loop mode. This means that it is relying on a set of internal calculations and data tables to decide how mu[...]

32 COOLANT (°F) (Engine Coolant T emperature - PCM input) COOLANT (°C) Display: Numeric temperature value: - 40 to 419 ( ° F) or -40 to 215 ( ° C). This is a measure of the engines coolant temperature. A voltage signal is sent to the PCM from a sensor that is in contact with the coolant. The voltage signal in- creases as temperature increase[...]

33 IA T TEMP (°C) (Intake Air T emperature - PCM input) IA T TEMP (°F) Display: Numeric temperature value: -40 to 419 ( ° F) or -40 to 215 ( ° C) This is a measure of intake air temperature to determine correct air/fuel ratios and spark timing operations. The voltage from a thermistor in the intake manifold is sent to the PCM. The PCM converts [...]

34 MAP (HG) (Manifold Absolute Pressure - PCM input) MAP (KP A) Display: numeric inches of Mercury (HG) or kiloPascals (KP A) The Manifold Absolute Pressure sensor converts intake manifold vacuum or pressure to an electric signal and sends it to the PCM. The PCM converts this signal into a numerical pressure value expressed in kiloPascals (kP[...]

35 SECONDARY AIR (Secondary Air System Status - PCM output) Display: UPSTR, DNSTR, A TMSP The secondary air injection system on newer vehicles is controlled by the PCM. The PCM use actuators to control this pollution control system. Secondary air can be added the exhaust system near the exhaust manifold (before any catalytic converts), at the catal[...]

36 A/C: Air Conditioning. A/F: Air/Fuel ratio. This refers to the proportion of air and fuel delivered to the cylinder for com- bustion. For example, if you have 14 times more air than fuel (by weight) then the A/F ratio is 14:1 (read as fourteen to one). The ideal operating A/F ratio in an automotive application is 14.7:1. AC Clutch Relay: T[...]

37 CKP REF: Crankshaft Reference. CKP: Crankshaft Position Sensor .

Most systems have the ability to store codes in memory , which are commonly referred to as history codes or s[...]

39 EGR: Exhaust Gas Recirculation. The EGR sys- tem recirculates exhaust gases back into the intake manifold to reduce NOx emis- sions. The EGR valve controls the flow of exhaust gases back into the intake mani- fold. Some EGR valves are operated with a vacuum signal while others are electrically controlled. The amount of EGR valve open- ing determ[...]

40 Hall Effect Sensor: This sensor is a three wire-type of sensor containing electronic circuitry . T wo wires supply power and ground, while a third wire carries the sensor signal back to the PCM. The sensor consists of a perma- nent magnet and a small module con- taining a transistorized Hall Effect switch. A small air gap separates the sensor an[...]

41 MAF: Mass Air Flow Sensor . This sensor mea- sures the amount of air entering the engine using a wire or film heated to a specific tem- perature. Incoming air cools the wire. The MAF sensor sends a frequency or voltage signal (depending on sensor type) to the PCM based on the voltage required to main- tain that temperature. The signal frequency [...]

42 delivered (The PCM assumes everything in the fuel system is performing properly). In open loop operation, the PCM does not check the actual amount of fuel delivered. Thus, a faulty fuel injector or incorrect fuel pressure can change the amount of fuel delivered and the PCM would not know it. In general, a control system operates in open loop mod[...]

43 PCM uses sensors to measure such things as throttle position, coolant temperature, engine speed, incoming air mass and tem- perature, etc. SFI or SEFI: Sequential Fuel Injection or Sequential Elec - tronic Fuel Injection. A fuel injection system that uses one or more injectors for each cyl- inder . The injectors are mounted in the in- take manif[...]

44 VIN: V ehicle Identification Number . This is the factory-assigned vehicle serial number .
