Error code 21 for a 1995 Chrysler Cirrus typically indicates an issue with the vehicle's oxygen sensor or the system's fuel mixture, specifically related to the signal from the oxygen sensor being out of range. This can lead to poor fuel economy and increased emissions. It's advisable to check the oxygen sensor and its connections for faults or damage, and consider replacing it if necessary. Additionally, ensure there are no exhaust leaks that could affect sensor readings.
