PGM-FI System

Engine Coolant Temperature (ECT) Sensor (cont'd)

The HDS or the scan tool indicates Diagnostic Trouble Code (DTC) P0125: Engine Coolant Temperature

(ECT) sensor malfunction/slow response.

Is about 86°F (30°C) or less, or

2.61 V or higher indicated?
Intermittent failure, system is OK

at this time.

Check the thermostat and the

cooling system.

YES

Problem verification:

1. Let it idle for 6 minutes.

2. Check the ETC output temper-

ature or voltage with the HDS

or the scan tool.

Is about 86°F (30°C) or less, or

2.61 V or higher indicated?
Intermittent failure, system is OK

at this time.

Check the thermostat and the

cooling system.

YES

Replace the ECT sensor.

11-50
Problem verification:

1. Start the engine, and let it idle.

2. Check the ETC output temper-

ature or voltage with the HDS

or the scan tool.
— The MIL has been reported on

— DTC P0125 is stored.ProCarManuals.com

The HDS or the scan tool indicates Diagnostic Trouble Code (DTC) P0133: A slow response problem in the Right

Primary Heated Oxygen Sensor (Right Primary H02S) (Bank 1, Sensor 1) circuit.

The HDS or the scan tool indicates Diagnostic Trouble Code (DTC) P0153: A slow response problem in the Left

Primary Heated Oxygen Sensor (Left Primary HO2S) (Bank 2, Sensor 1) circuit.

Description

By controlling the air/fuel ratio with a Primary HO2S (Sensor 1) and a Secondary HO2S (Sensor 2), the deterioration of the

Primary H02S (Sensor 1) can be evaluated by its feedback period. When the feedback period of the H02S exceeds a certain

value during stable driving conditions, the sensor will be judged as deteriorated. When deterioration has been detected dur-

ing two consecutive trips, the MIL comes on and DTC P0133 or P0153 will be stored.

NOTE: If DTC P2195, P0134, P2297 and/or P0135 are stored at the same time as DTC P0133, troubleshoot those DTCs first,

then troubleshoot DTC P0133. If DTC P2197, P0154, P2298 and/or P0155 are stored at the same time as DTC P0153, trou-

bleshoot those DTCs first, then troubleshoot DTC P0153.

Possible Cause

• Primary HO2S (Sensor 1) Deterioration

• Primary H02S Heater (Sensor 1) Deterioration

• Exhaust system leakage
Primary Heated Oxygen Sensor (HO2S) (Sensor 1)

The Heated Oxygen Sensors (HO2S) detect the oxygen content in the exhaust gas and signal the PCM. In operation, the

PCM receives the signals from the sensor and varies the duration during which fuel is injected. To stabilize the sensor's

output, the sensor has an internal heater. The Right Primary HO2S (Bank 1, Sensor 1) is installed in the right exhaust man-

ifold, and the Left Primary HO2S (Bank 2, Sensor 1) is installed in the left exhaust manifold.ProCarManuals.com

System Description (cont'd)

Global Positioning System (GPS)

The Global Positioning System (GPS) enables the navigation system to determine the current position of the vehicle by

utilizing the signals transmitted from the satellites in orbit around the earth. The satellites transmit the satellite identifica-

tion signal, orbit information, transmission time signal, and other information. When the GPS receiver receives a signal

from three or more satellites simultaneously, it calculates the current position of the vehicle based on the distance to each

satellite and the satellite positions on their respective orbits.

Position detection Image with GPS satellite
Navigation System

Precision of GPS

The precision of the GPS varies according to the number of satellites from which electric waves are received and the con-

trol condition. The precision is indicated by the color of the GPS icon shown on the upper right of the display.

GPS Antenna

The GPS antenna amplifies and transmits the signals received from the satellites to the GPS receiver.

GPS Receiver

The GPS receiver is built in the navigation unit. It calculates the vehicle position by receiving the signal from the GPS

antenna. The vehicle position and signal reception condition is transmitted from the GPS receiver to the navigation control

unit to adjust vehicle position.ProCarManuals.com

Navigation System

System Diagnosis Mode (cont'd)

Black Raster

The entire display must be shown in black.

Test Pattern

The chart below; shows the colors being used for the

map and menu screens. This is for factory use only. To

check the color signal use the "RGB Color" diagnostic

found under the Monitor Check menu item.

Monitor Adjustment

This allows the navigation display to be centered. Use

the joystick to move the picture up/down or left/right. It

is unlikely that you will ever need to adjust the monitor

position. The "Default" button will reset the display

position to factory specifications.
Touch Panel

The panel touch sensing system consists of 9 horizontal

and 20 vertical infrared beams. Touching the screen

blocks both a horizontal and a vertical beam. Every pos-

sible touch position is shown on this diagnostic screen.

Touching one of these areas should cause its color to

reverse, and sound a "beep". If any areas of the screen

either don't respond, or respond at some other location

when touched, then replace the display unit. The

"Display" diagnostic listed in Unit Check provides an

additional method to determine if one of the infrared

sources or detectors is bad.

NOTE: Direct sunlight can affect this test by falsely trig-

gering the infrared detectors, so perform this diagnostic

inside or in a shaded area.ProCarManuals.com

Removal (cont'd)

11. Remove the bearing from the cap. Keep all caps/bear-

ings in order.

12. Remove the upper bearing halves from the connecting

rods, and set them aside with their respective caps.

13. After removing each piston/connecting rod assem-

bly, reinstall the cap on the rod.

14. To avoid mixup during reassembly, mark each pis-

ton/connecting rod assembly with its cylinder num-

ber.

NOTE: The existing number on the connecting rod

does not indicate its position in the engine, it indicates

the rod bore size.

15. Remove the bearing cap bolts and bearing cap side

bolts, then remove the bearing cap.
