Replaced with new. Both original & new MAP no volt decrease when testing for voltage drop w/ DVOM and handheld vacuum pump.
After seeing a detailed video and testing my MAP sensor on my '99 SL2 DOHC Vin#7. I saw no voltage drop when applying a vacuum on the MAP sensor both new and old. Voltage stayed steady at 5V. I tested the connector without the MAP connected and tested each metal probe to ground and got the proper readings. I was told to check the wiring back to the PCM. Where is the PCM and or how else can I check/diagnose and fix this issue?
Thanx in advance for your help.
have the same problem?
