Cooling Fan 1 Control Circuit Low. When the temperature reaches about 223 degrees f value depends on make model engine the pcm will command the cooling fan relay to turn on the fan. This code is a generic trouble code meaning it applies to all vehicles equipped with the obd ii system especially those made since 1996 up to present.
The level can be too high or too low. What causes the p0691 code. What does that mean.
The p0481 nissan code is detected when the pcm detects that the commanded state of the driver and the actual state of the control circuit do not match.
The p0691 code appears when the powertrain control module pcm has detected an inappropriate level of voltage in the electric cooling fan s control circuit. What causes the p0691 code. Error code p0480 refers to the basic circuit and its related codes error code p0481 and error code p0482 relates to similar problem but specific to different fan speed relays. Basically the error code p0480 means the cooling fan 1 control circuit has experienced a problem causing it to malfunction.
