You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

U1052 Possible Solution:

U1052 Engine

Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.

U1052 Code Meaning :

U 1 0 5 2
OBD-II Diagnostic Network (U) Trouble Code For Engine Fuel And Air Metering Ambient Air Temperature Sensor Circuit Low Cylinder 1 Injector Circuit Low Glow Plug/Heater Circuit 'A' Malfunction

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

U1052 OBD-II Diagnostic Network (U) Trouble Code Description

U1052 engine trouble code is about Glow Plug/Heater Circuit 'A' Malfunction.

Reason For U1052 Code

The reason of U1052 OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.

U1052 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
