Here’s a list (click on to see info and purchase product)
1. Mass Air Flow (MAF) Sensor
- Location: Intake air ducting
- Purpose: Measures the amount of air entering the engine for optimal fuel-air mixture.
2. Manifold Absolute Pressure (MAP) Sensor
- Location: Intake manifold
- Purpose: Monitors intake manifold pressure to help regulate turbo boost and fuel injection.
3. Engine Coolant Temperature (ECT) Sensor
- Location: Near the thermostat housing
- Purpose: Monitors engine coolant temperature to help adjust fuel mixture and monitor overheating.
4. Intake Air Temperature (IAT) Sensor
- Location: Air intake system (often combined with the MAF sensor)
- Purpose: Measures the temperature of incoming air to adjust fuel injection.
5. Crankshaft Position Sensor
- Location: Near the crankshaft, typically at the engine’s front
- Purpose: Monitors the position and rotational speed of the crankshaft for ignition timing and fuel injection.
6. Camshaft Position Sensor
- Location: Near the camshaft
- Purpose: Tracks camshaft position to control the timing of fuel injection and valve operation.
7. Turbo Boost Pressure Sensor
- Location: On the turbocharger or intake manifold
- Purpose: Measures boost pressure generated by the turbocharger for proper boost control and fuel management.
8. Exhaust Gas Recirculation (EGR) Position Sensor
- Location: On the EGR valve
- Purpose: Monitors the position of the EGR valve to regulate exhaust gas flow back into the intake system for emissions control.
9. Oxygen (O2) Sensor
- Location: In the exhaust system
- Purpose: Monitors the amount of oxygen in the exhaust gases to adjust the air-fuel mixture for emissions and fuel efficiency.
10. Fuel Temperature Sensor
- Location: On the fuel rail
- Purpose: Measures fuel temperature to adjust injection timing and fuel pressure.
11. Fuel Pressure Sensor
- Location: On the fuel rail or fuel line
- Purpose: Monitors fuel pressure to help maintain optimal injection pressure.
12. Brake Pedal Position Sensor
- Location: Near the brake pedal assembly
- Purpose: Senses brake pedal position, impacting ABS and other braking systems.
13. Throttle Position Sensor (TPS)
- Location: On the throttle body
- Purpose: Monitors throttle position for acceleration control and to regulate air intake.
14. Ambient Air Temperature Sensor
- Location: Usually near the front bumper or under the hood
- Purpose: Measures outside air temperature, often for climate control adjustments.
15. Vehicle Speed Sensor (VSS)
- Location: On the transmission or differential
- Purpose: Tracks vehicle speed, used by the ECU for shifting points in automatic transmission and ABS.
16. Wheel Speed Sensors (ABS Sensors)
- Location: At each wheel hub
- Purpose: Measures each wheel’s speed, used by ABS and traction control systems.
17. Transmission Fluid Temperature Sensor
- Location: Inside the transmission
- Purpose: Monitors transmission fluid temperature for shifting and performance adjustments.
18. Oil Fill level sensor
19. Aftermarket Add On TPMS Sensors
20. Brake Pad Wear Sensor
These sensors work together to maintain optimal engine, transmission, and overall vehicle performance by feeding data to the van’s ECU. Replacing or maintaining them can prevent issues with driveability and fuel efficiency.sive list of sensors for the T1N 2002-2006 Sprinter Van (Dodge/Freightliner/Mercedes):
