P194E Hillman Imp Diagnostic Trouble Code
P194E Hillman Imp code definition:
P194E is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Hillman Imp.
P194E Hillman Imp is described as Oxygen Sensor Circuit No Activity Detected (Bank 1, Sensor 1). This means there's a problem in the front oxygen sensor on Bank 1, as the O2 sensor is inactive. Other serious codes may cause this code to pop up, and they may come with dangerous drivability issues that may expose you to safety risks and cause damage to the engine in the long run.
Symptoms
Symptoms of a P194E Hillman Imp diagnostic trouble code may include:
- Faulty or damaged wiring
- 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
- Poor fuel economy
- The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :
- Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.
- Rarely - faulty Powertrain Control Module (PCM-programming required after replacement)
- A large vacuum leak would cause a massive amount of un-metered air to enter the intake manifold resulting in an overly lean mixture.

Common Misdiagnoses
- Control Module Throttle Actuator Position Performance Problem
- Air Conditioning (A/C) Clutch Feedback Circuit High Voltage Problem
- Cruise Vehicle Speed/Set Speed Difference Too High Problem
- Kick-Down Switch Failed Short Problem
- Park/Neutral Postion (PNP) Switch Circuit Engine Torque Signal Circuit Problem
Repair Processes :
Look at the plug wires to make sure they are not burnt or laying on the exhaust.
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.
If you find a related TSB, the information will often help in diagnosing the code in question as TSBs are crested from many thousands of repairs.
