Can a car stall if there is no DTC?
If your car’s computer hasn’t thrown any DTCs, you may want to check the following potential components or systems to find the fault. An engine can stall under different conditions, depending on the specific fault. For example, the engine may stall during acceleration, while idling, after reaching operating temperature, or stall intermittently.
What does DTC stand for on a car?
Let’s start by explaining the DTC meaning first. DTC stands for Diagnostic Trouble Codes. A DTC code is a series of diagnostic trouble codes used by a vehicle’s onboard diagnostics (OBD) system to alert you when a vehicle experiences a malfunction.
How long is a non critical DTC code?
Non-critical codes include those that light up the Malfunction Indicator Lamp (MIL), also known as the Check Engine Light. Type two codes also store a freeze-frame that has failed consecutively after two driving cycles. A DTC code is five characters long.
What happens if a DTC is deleted from a car?
If the DTC is just deleted, the system may not reset the DTC until a certain distance is travelled. This means the system may not be functioning correctly. Another example would be if parts were removed from a vehicle during the repair process and the DTCs were for loss of communication with those parts.

How is DTCs used to diagnose car problems?
Since 1982, the On-Board Diagnostic (OBD) system has helped automotive technicians monitor and find problems with emission components or control systems that may have gone out of their normal operating parameters. A car’s computer uses DTCs to pinpoint a potential system’s fault.
What causes a car engine to stall after starting?
Engine stalling shortly after starting. The engine hesitates or drags while under load or idle. Hesitation and jerking during acceleration. The engine hiccups. Excessively rich or lean idling. A sensor that has been contaminated by fuel, varnish or dirt will under report airflow.
What is the fault code for a Caterpillar C-9 truck?
Discussion in ‘ Peterbilt Forum ‘ started by elimy, May 20, 2015 . I am looking for a list of fault codes for a Caterpillar C-9 truck engine with serial number prefix 9DG. I did find a partial list for a 3176B, C-10, C-12, 3406E, C-15 and C-16. Are they the same for a C-9? Every month 400 people find a job with the help of TruckersReport.
Can a faulty manifold sensor cause engine stall?
A faulty manifold pressure sensor has symptoms that closely resemble; a vehicle with injector problems or low compression problems. If the (MAP) sensor is not reading accurately; the (PCM) may add too much fuel or not enough. This again will cause engine stalling.
