How to Replace TMAP Sensor for Kohler ECH440 EFI System

How to replace Temperature/Manifold absolute pressure (TMAP) sensor for Kohler ECH440 EFI System.

2024 Kohler Kira Integrated Remote Analytics 2.6.0.0

KOHLER EFI Diagnostic 2.11.0013

A sealed non-serviceable integrated sensor that checks both intake air temperature and manifold absolute pressure. Complete replacement is required if it is faulty.

Sensor and wiring harness can be checked as follows.
If a fault code indicates a problem with Intake Air Temperature (TMAP) Sensor Circuit (P0112 or P0113), it can be tested as follows:
1 Remove TMAP sensor from throttle body.
2 Allow it to reach room temperature (20°C, 68°F).
3 Unplug Black connector from ECU.
4 With sensor still connected, check temperature sensor circuit resistance between Black pin 10 and 8 pin terminals. Value should be 1850-2450 Ω.
5 Unplug sensor from wire harness and check sensor resistance separately across pin. Resistance value should again be 1850-2450 Ω.
a If resistance is out of specifi cations, check local temperature. Sensor resistance will go down as
temperature is higher. Replace TMAP sensor if determined to be faulty.
b If it is within specifi cations, proceed to Step 6.

6 Check circuits (input, ground), from main harness connector to sensor plug for continuity, damage, etc.
Connect one ohmmeter lead to Black pin 8 in main harness connector (as in step 4). Connect other lead to terminal #3 in sensor plug. Continuity should be indicated. Repeat test between Black pin 10 and terminal #4 in sensor plug.
7 Reinstall sensor.

If a fault code indicates a problem with Manifold Absolute Pressure (TMAP) Sensor Circuit (P0107 or P0108), it can be tested as follows:
1 Make sure all connections are making proper contact and are free of dirt and debris. Slide locking
tab out and pull off TMAP connector. Turn key switch to ON and check with a volt meter by contacting red lead to pin 1 and black lead to pin 2. There should be 5 volts present, indicating ECU and wiring harness are functioning.

2 Check continuity in wire harness. Ohms between Pin 3 at sensor connector and Black pin 11 connector at ECU should be near zero ohms. If no continuity is measured or very high resistance, replace wire harness.

3 Check to make sure throttle body is not loose and TMAP sensor is not loose. Loose parts would allow a vacuum leak, making TMAP sensor report misleading information to ECU.
a Tighten all hardware and perform an ECU Reset and a TPS Learn Procedure to see if MIL will
display a fault with sensor again. If MIL finds a fault with TMAP sensor, replace it.

CLAAS CDS 7.5 Diagnostic System 2021.05

Procedures:

Repairing the cylinder block

Checks and measurements of the liners

Check the internal diameter of the cylinders for runout, tapering and wear, using a gauge (2) with a dial gauge (1), set to zero on the ring gauge (3) with a diameter of 117 mm.

NB: If you do not have a ring gauge with a diameter of 117 mm available, use a micrometer.

Measurements must be taken for each cylinder at three heights along the liner and on two perpendicular levels “A” and “B”.

Replace the cylinder if the maximum wear differs by 0.150 mm or the maximum runout by 0.100 mm from the values indicated.

Do not attempt to correct or deglaze.

NB: The cylinders are provided as spares with selection class “A”.

CAUTION
• Stop the engine when adjusting the cruise control linkage and pedal stroke.
NOTE
• Be sure to adjust the HST neutral position.
• Be sure to check whether the “traveling speed coefficient” is suitable for tire size.
1. Loosen the HST pedal mounting screws (4) and tighten the screws (4) while pulling up the front of HST pedal (1).
2. Adjust the height a of the pedal stopper bolt (Forward) (3) to approx. 25 mm (0.98 in.) from the step.
3. Operate the tractor actually and make whether the tractor can put on sufficient speed.
4. Set the cruise control lever to fully forward (Maximum position).
HST pedal also tilts.
5. Measure the clearance b between bottom of HST pedal and tip of pedal stopper bolt (Forward) (3).

6.If the measurement is not within factory specification, adjust by the cruise adjusting rod (5). (Cruise Linkage Adjustment.)

7.Shorten the pedal stopper bolt (Reverse) (2) to the position where the length of the bolt is not touched to the HST pedal (1) even if the HST pedal is fully depressed rearward.
8. Lengthen the length of the pedal stopper bolt (Reverse) (2) gradually with the HST pedal fully depressed rearward to contact to the HST pedal.

Caterpillar C9 Engine 15 164-2 Injection Actuation Pressure Signal Erratic

The Engine Control Module(ECM) detects the following conditions:

The injection actuation pressure is greater than 3 MPa (435 psi) for more than three seconds when the engine is off.

The difference in the actual pressure and the desired pressure is greater than 2 MPa (290 psi) for more than ten seconds with the engine running.

Actual rail pressure is between 11.0 MPa (1595.41 psi) and 17.4 MPa (2523.66 psi) for more than ten seconds.

Sensor current changes more than0.075 Amp and rail pressure changes less than 0.5 MPa (72.5 psi) with the engine on.

The engine is not running and the ECM has been powered for at least four seconds.

Cold mode is not active.

Engine speed is 0 rpm for more than 3 seconds and the engine is not running.

The injection actuation pressure sensor measures the pressure of the oil in the high pressure oil manifold. The high pressure oil in the manifold is used to actuate the injectors and the high pressure oil is used to control the fuel injection pressure. Fuel injection pressure is based on inputs from the sensors. The inputs are used by the Engine Control Module (ECM) for calculating the fuel injection pressure. The ECM uses the reading from the injection actuation pressure sensor in order to control the operation of the injection actuation pressure control valve.
