MAF and IAT Sensor InspectionS7RS0B1306020
CAUTION!
Do not heat up MAF and IAT sensor more
than 100 °C (212 °F). Otherwise, MAF and IAT
sensor will be damaged.

• Check sensor O-ring (1) for damage and deterioration. Replace as necessary.
• Blow hot air to temperature sensing part (2) of MAF and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.
IAT sensor resistance
–20 °C (–4 °F): 13.6 – 18.4 k Ω
20 °C (68 °F): 2.21 – 2.69 k Ω
60 °C (140 °F): 0.493 – 0.667 k Ω

Inspection
S7RS0B1306021
Using SUZUKI Scan Tool
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Check “Battery Current” displayed on scan tool at following condition.
Battery current
Ignition switch ON: 6.5 – 7.5 A
Ignition switch ON, headlight ON: 18.6 – 19.1 A
Ignition switch ON, headlight ON and blower
motor switch is HI position: 27.1 – 27.6 A
Engine running at idle speed, headlight ON,
blower motor switch is HI position and rear
defogger switch ON: 38.1 – 41.7 A
If check result is satisfactory, electric load current sensor
is in good condition.
If check result is not satisf actory, check the following
parts and circuit.
• Electric load current sensor circuit (power, ground and output)
• Following charging system components
– Battery (refer to “Battery Inspection in Section 1J”)
– Generator (refer to “Generator Inspection in Section 1J”)
– Generator output control ci rcuit (refer to “Generator
Test (Undercharged Battery Check) in Section 1J”)
– Generator field coil monitor circuit (refer to “Generator Inspection in Section 1J”)
If electric load current sensor circuit and charging
system is in good condition, electric load current sensor

sensor is in good condition.
If check result is not satisfactory, check the following
parts and circuit.
• Electric load current sensor circuit (power, ground and output)
• Following charging system components – Battery (refer to “Battery Inspection in Section
1J”)
– Generator (refer to “Generator Inspection in Section 1J”)
– Generator output control circuit (refer to “Generator Test (Undercharged Battery Check)
