Question about 1992 Volvo 940
Srs light on will no clear
***WARNING*** working on the SRS is dangerous if procedure is not followed exactly. Read this carefully: Electrical Air Bag SRS, and follow it to the letter. Depending on year your reset procedure for the SRS may vary, either by using the diagnostic connection under the hood or by using a jumper wire on the SRS test connection in the main electrical distribution block behind the ashtray.
2-3-2 is the OBD1 code for Incorrect Mixture Ratio: The system has compensated swiftly by additive computation and is at adaptive limit (too rich, check fuel pressure regulator and its vacuum connection to start). The other code (2-3-1) means multiplicative adaptation has taken place at idle (slow adaptation) and is at limit. Both codes usually indicate the oxygen sensor is no longer doing its job or there are major vacuum leaks in the system, usually near the intake manifold or throttle body.
