Diagnostic Trouble Code
P0210
Cylinder 10 Injector Circuit Malfunction
Technical Description P0210
Cylinder 10 Injector Circuit Malfunction
What Does This Mean P0210?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
P0210 means that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled "low" or close to zero.
When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or "high". If it doesn't see the expected voltage the PCM will set this code. The PCM also monitors resitance in the circuit. If the resistance is excessively low or high it will set this code.

Possible Causes P0210
1
Bad injector. This is usually the cause of this code but doesn't rule out the possibility of one of the other causes
2
Open in the wiring to the injector
3
Short in the wiring to the injector
4
Bad PCM
