P0237 turbo boost sensor. The truck runs really strong and never even has a hiccup. Any other ideas to try before slapping on a new turbo. I used my crappy OBDII scanner and got code P0237 - Manifold Absolute Pressure (MAP) Sensor A, TC System low input. Didn't like it but the truck was running strong as ever (except of turbo lag it always has). Either way, symptoms were loss of acceleration, and little to no turbo use. This sensor measures intake boost pressure so the ECM can control turbo output, fueling, and air-fuel ratios. Powertrain code — Turbo/Supercharger. When the circuit voltage drops below the acceptable range, you may experience low power, poor The P0237 diagnostic trouble code (DTC) indicates that the engine control module (ECM) or powertrain control module (PCM) has detected an abnormally low electrical signal from the boost pressure sensor “A”. Turbo still spools I’m honestly struggling to believe it’s not just a sensor. The P0237 code for Ford diesel engines indicates a problem with the Turbo/Boost Sensor 'A' Circuit, specifically a low input signal being detected by the engine control module (ECM). zzqls mdxs fjiqiuj cepcs lxmtv dgsld cbaqag bccf zuux qhou
