Volvo All Engines (2017 Emissions) Fault Code: P205B64 PID: ACM Reductant Tank Temperature Sensor Circuit Range Performance - EcuForce Truck (2024)

FAQs

What is the code P205B64 on a Volvo? ›

The P205B64 is a fault code for the reductant tank temp circuit range. This has to do with def tank temp changes.

The reductant temp sensor is the def level/temp sensor that is in the def tank on this unit.

P205B OBD-II code: Reductant tank temperature sensor issue.

Wait and Reconnect: Leave the battery disconnected for about 15-30 minutes. This allows the car's computer to reset. After the waiting period, reconnect the negative terminal and tighten the nut securely. Turn on the Ignition: Turn the car's ignition to the "ON" position without starting the engine.

The EVAP system will monitor pressure; the pressure should drop briefly before building up in the fuel tank system. If for some reason this test is not done within a reasonable time, the diagnostics will abort and a Check Engine light will set.

The average cost for a Fuel Temperature Sensor Replacement is between $272 and $315. Labor costs are estimated between $164 and $207 while parts are typically priced around $108. This range does not include taxes and fees, and does not factor in your unique location.

it should be as long as the mileage countdown doesn't start on the dash. May might've different exhaust smell and slightly lower MPG but other than that it will be fine. No problem.

The Urea Quality Level Sensor (UQLS) is a smart sensor that is located in the top of the Urea (DEF) Tank, commonly referred to as the DEF Level Sensor or Combined Tank Unit. This smart sensor has Urea Quality, Level, and Temperature all integrated into it as one unit and reports on the DL7 (J1939-7) Datalink.

The reductant tank is the diesel exhaust fluid tank. The p0205b code is becoming more and more common on these trucks. It sets when the temperature sensor in that tank malfunctions.

The reductant heater is a component that is used to prevent diesel exhaust fluid from freezing or crystallizing in low temperatures. It is usually located in the diesel exhaust fluid filter reservoir and/or the reductant injector supply hose(s).

What code does a bad engine coolant temp sensor throw? ›

The P0118 code refers to issues with the Engine Coolant Temperature (ECT) circuit and its accompanying sensor. The ECT is a thermistor, or an electrical resistor, whose resistance is significantly reduced by heating.

A logged P0524 trouble code means that the powertrain control module (PCM) has detected critically low oil pressure level in the engine. A damaged oil pressure sensor and faulty oil pump are two of the most common reasons why this code can appear.

The P205B code stands for “Reductant Tank Temperature Sensor Circuit Range/Performance”, which means the power control module (PCM) didn't get the right response from the reductant tank temperature sensor.

The P0117 code stands for “Engine Coolant Temperature (ECT) Sensor 1 Circuit Low”, which means your powertrain control module has detected a low voltage input from ETC sensor 1. A defective ETC sensor, air pockets in the coolant system, and other cooling system issues are some of the common causes of the P0117 code.
