Overview:

DTC Description (User Friendly)

P0098-15: Intake Air Temperature Sensor 2 Circuit High: Air

intake manifold temperature (circuit short to battery or open).

ECU Pin Number

A038, A096, A095, A061

Customer Symptom

MIL ON, CEL OFF.

Fault Effects (On Vehicle)

Lamp Status (If Any)

MIL ON. MIL Turns Off as and when fault condition is not

present / healed.

Fault Detection Condition (Root cause)

1. This DTC gets logged if EMS intake air temperature 2

(Boost Temperature) input pin no 61 gets short

circuited to battery / open circuited.

2. The sensed raw voltage value of the engine Inlet

valve upstream air temperature is above threshold99

(4903 volt).

Normal Operating Condition

Proper wiring harness connections between Intake Air

Temperature sensor 2 (Boost Temperature Sensor) and EMS

ECU.

Probable Trouble Area

Wiring Harness connections between EMS ECU & Boost

temperature sensor

Healing Condition

Rectify the error

Clear through diagnostic tool

Component Details:

Boost Temperature sensor is a NTC sensor which provides the Boost air temperature to EMS ECU.

Preliminary Checks:

1. Check whether the customer voice / view about the issue is matching with the fault effects mentioned in above

Table. If yes, go ahead with next steps. If not, check for other DTC’s presence.

2. Check whether other customers report similar complaints earlier. If yes, perform the preliminary checks with

respect to earlier issue closure.

3. Check for Damage in EMS ECU connector / Boost Pressure & Temperature sensor connector.

4. Check for any back out of pins at EMS ECU connector / Boost Pressure & Temperature sensor connector.

5. Check for any damage of pins at EMS ECU connector / Boost Pressure & Temperature sensor connector.
