- Has faults stored: EOBD/OBDII – P0125 – Insufficient coolant temp. for closed loop fuel control P2441 – AIR system switching valve stuck closed, B1 P2443 – AIR system switching valve stuck closed, B2 P2445 – AIR system pump stuck off, B1 ECMECT – P0118 – Engine coolant temperature circuit, high input, pending P0118 – Engine coolant temperature circuit, high input, current P0118 – Engine coolant temperature circuit, high input, history ABS – C1405 – Open or short in front speed sensor, RH circuit C1408 – Open or short in front speed sensor, LH circuit Disconnected aftermarket box in-line with MAF sensor, no change with run-ability. Monitored engine data with engine running – MAF within spec. Coolant temp sensor reads -40* with engine at operating temp, temp gauge in cluster inop. *When P0118 is stored, the ECM enters fail-safe mode. During fail-safe mode, the ECT is estimated to be 80°C (176°F) by the ECM. Fail-safe mode continues until a pass condition is detected.* Fully removed aftermarket MAF box/wiring – engine runs much better and coolant temperature gauge now works, but ECM still stored secondary air injection faults. Found three blown fuses – replaced, no change. Found loose ground on back of B1 cylinder head and re-tightened. Ran secondary air test plan via scan tool – faults did not return at this time. It does now have P2198 fault stored for B2S1 O2 sensor stuck rich – suspect either sensor issue or due to many exhaust leaks audible when engine running. Secondary air faults returned on cold start – most likely will need valves replaced but does pass function test without issues.
