Symptoms
Symptoms of a U0271 Reliant Kitten diagnostic trouble code may include:
- The engine oil will exhibit dilution from the ECUs attempts to increase engine temperature. Some vehicles advance the fuel injection timing slightly after top center to afterburn a small amount of fuel to increase exhaust temperatures. Some of this fuel enters the crankcase. When the ECU determines the necessity to regenerate the DPF, the service life of the oil be shortened significantly
- Faulty or damaged wiring
- Hesitation upon acceleration
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- An air leak forward of the DPF will change the sensor readings resulting in the code

- Crankshaft Position Sensor Circuit Performance Problem
- TP Sensor Learn Not Complete Problem
- Low Coolant Circuit Problem
- Cruise Control System - Vehicle Accel Too High Problem
- Kick-Down Switch Failed Short Problem
Repair Processes :
It should be pretty close to battery voltage (12 volts). If not, then this is the circuit that has the problem.
With the valve disconnected, the red voltmeter lead should be attached to the IMRC valve power wire and the black voltmeter lead connected to ground.
Oxygen sensors signal the engine management computer the amount of oxygen present in the exhaust, which is used in determining and controlling the fuel ratio.
